Electrical maintenance in critical installations is a fast moving discipline, with increasingly strict regulation and many new technologies. It can be difficult to balance the objectives of eliminating hazards to personnel and ensuring a reliable supply with the restrictions of tight budgets.
You don't have to take our word for it. Our work at nuclear power installations means that we are pre-qualified to the highest possible level for a supplier who works on operational sites owned, managed or controlled by utilities in the UK (UVDB verify, category B2). UVDB is the utility industry pre-qualification system used across the UK. This system helps utilities achieve the highest standards of supply chain assurance.
Electronic equipment operating normally can induce DC earth-leakage current in circuits. EV charging equipment is one common source of DC earth-leakage current.
Type A RCDs typically provide upstream protection for multiple EV chargers. They protect against AC earth-leakage current but do not provide protection from excess DC earth-leakage current. This is not necessary when Type B RCDs are the first line of protection. However, the operating coils of some type A RCDs can be saturated by DC earth-leakage current. This can have an impact on their ability to operate correctly. This phenomenon is known as “blinding”.
Our downloadable guide explains the causes of blinding, and offers solutions.

4 Questions Answered About Switchgear for Large Solar Plants
The trend in solar power generation is to collect power at higher voltages. In principle higher voltages minimise power loss in cables. Here we answer 4 questions about switchgear for those voltages.
1Is there a range of circuit breakers for use at 800V AC?
Terasaki have Air Circuit Breakers (ACBs) and Moulded Case Circuit Breakers (MCCBs) suitable for 800V AC
2 I need switchgear to feed a 5MVA transformer. It should collect power from 25 inverters of 185kW each. This is a big system. 3600A. Is there a main circuit breaker that can handle this power at 800V AC?
Terasaki have launched the AR440SB-V8 Air Circuit Breaker. It can handle the power input to a 5MVA transformer at 800V AC. You can use it as the main outgoing ACB feeding a transformer in a large solar generation plant.
3I’m worried about short-circuits. Can circuit breakers work properly when the fault level is 30kA or 50kA at 800V AC?
Terasaki have circuit breakers which can safely interrupt short-circuit currents of up to 50kA at 800V AC. The new AR440SB-V8 can handle this fault current.
4 I don’t want to experiment. Is this technology tried and tested?
Terasaki have short-circuit-tested their range of 800V circuit breakers at independent test laboratories. Top-rated solar plant developers like ANESCO in the UK have used Terasaki circuit breakers to protect their equipment.

Terasaki supports your 'right to repair' (we always have)!
Recent UK government legislation raises the bar for reducing energy consumption and improving product lifespan by designing in repairability. The regulations which cover domestic white goods, televisions and some commercial appliances, enshrine in law that manufacturers are required to make spare parts for products available to help extend the lifespan of products and reduce non-recyclable waste.
Although circuit breakers are not yet included in such legislation, design for repair and design for service have long been a part of Terasaki’s design philosophy. Further, there is no built-in obsolescence with our products with circuit breakers powering and protecting your operations trouble free for decades.
Terasaki has leadership in supplying circuit breakers to the marine industry for good reason. The industry demands ease of fitting, ease of repair, long product life, ease of replacement and short turnaround for maintenance.
Born of our heritage in meeting the exacting demands of the marine industry, Terasaki breakers have a number of exclusive innovations not provided by other manufacturers.
TemPower 2 key components are repairable on-site by the user
Our double break contacts
Tempower 2 design incorporates its isolating clusters and racking mechanism on the ACB body
Designed for long trouble-free life – Mean Time Between Failures (MTBF)
ACBs – 27.4 years
MCCBs – 26.5 years
Protection Relays and Accessories

Who Else Wants to Reduce Electrical System Downtime in Hospitals?
NHP, Terasaki's partner in Australia, has recently released a case study featuring Terasaki AR ACBs. You can view the video below:
The power distribution infrastructure at Monash Medical Centre in Melbourne was end of life and needed to be replaced. NHP met with the hospital to understand their requirements and recommended a SMART closed transition switch solution made possible by the Terasaki ACB, which guarantees a seamless transition from mains power to generator. This has reduced the need for months of planning for when the hospital undertakes mandatory quarterly testing of its generators, all the while keeping patient safety at the forefront.
Please visit the project references section on our website for more examples of case studies/projects where our TemPower 2 ACBs have been applied.
From the design office to the factory floor, quality is part of the ethos by which we all operate at Terasaki.
Quality overarches design for manufacture, design for maintainability, manufacture for reliability and results in long and trouble-free product life for our customers.
It’s in our corporate DNA.
Take, for example, our TemPower 2 ACB range.
Elegant design includes unique features such as: -
Our "Double Break" contact system ensures extremely fast interruption of short circuit currents. Energy is dissipated at two points on each pole within the breaker resulting in minimised erosion of the contacts and increasing the reliability of the breaker.
Our proprietary active sensor system continually monitors temperature of the conductors at the contacts and can signal an overheating alarm before irreversible damage occurs.
Uniquely, TemPower 2 ACBs have their isolating clusters and racking mechanism on the ACB body rather than the chassis. Having all the maintenance touch points on the body side allows shorter time to repair (MTTR) and minimal downtime.
But don’t just take our word for it, download the pdf to reveal more detail of these innovative features. Take a look at the testimonials of our customers in critical applications, harsh environments and remote installations.
Direct operation of switchgear is one of the most frequent exercises that exposes an operator to risk.
Remote switching permits operation of the circuit breaker at a safe distance.
Circuit breakers can be opened and closed from a remote location, removing the operator from the area of risk, and allowing a reduction in the level of personal protective equipment (PPE) required for the operation.
Using the Terasaki ACB remote controller provides a safer operating environment for personnel through the proven method of adding distance between the operator and the risk.
You can significantly reduce the cost of equipment for large solar farms by spending less on cable. Developers want to achieve this by transmitting power at higher voltages. Lower currents will be carried to the “collector” switchgear by cable with smaller cross-sectional area and lower cost. The trend is to transmit at 800V AC.
Terasaki support this opportunity for developers to reduce cost. We’ve type-tested a new range of circuit breakers for 800V AC. The VE400-NE MCCB and AR3H-V8 ACB handle fault currents up to 30kA at 800V AC. Current ratings from 100A to 3200A.
Following the recent successful roadshow we have taken on board customer feedback and have developed the GroupStak to include the following features:
Form 3b solution.
The GroupStak switchboard is now developed to include a form 3b option.
This offers a higher stacking density at lower price than the standard form 4b version. Maximum number of feeders of different types are listed below:
56 - single pole MCCBs, max 125A
21 - 3 pole MCCBs, max 160A
17 - 3 pole MCCBs, max 250A
12 - 3 pole MCCBs, max 400/630A
GroupStak is now design verified with outgoing MCCBs with electronic protection.
TemBreak 2 MCCBs from 250A frame to 630A frame are available with electronic protection units. Current ratings, In, of 40A, 125A, 160A, 250A, 400A, 630A are available. These offer flexibility as their characteristics can be set between 0.4 and 0.1 times In.
Every TemBreak 2 electronic protection unit includes overload protection (L), delayed short-circuit protection (S) and instantenious protecion (I) as standard.
Metering and CTs
Metering and CTs
GroupStak has now been developed to accept Rayleigh’s Easywire plug and play meters and CT's.
The steel work is pre-drilled for ease of mounting with pre-cut clear cover plates and door cuts-outs on request.
Many specifications request provision for future additions (spare ways). GroupStak can have spare ways included without MCCBs fitted. They have pre-coppered to the main bus bar making it a quick and easy job to add future MCCB outgoing devices.
