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. High Reliability and Safety at SeaVisit us at SMM Hamburg 2022

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.
Terasaki’s ACBs and MCCBs are backed up by our renowned Direct Response Service Division providing fault diagnosis and circuit breaker maintenance and repair where you need it, when you need it with minimal disruption to your operations.

Please contact us if you require more information How 800V AC on Large Solar Farms Reduces CostYou 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.
