Universal Circuit Breakers

Universal Circuit Breakers

KYW3 series universal circuit breakers are suitable for AC power distribution networks at 50/60Hz, with rated current from 200 to 4000A, rated insulation voltage of 1000V, and rated operational voltage of 400V/690V AC.

They distribute electrical energy and protect circuits and equipment from overload, undervoltage, short-circuit, single-phase ground faults, and other hazards, while also providing isolation. Featuring multiple protection functions, they support selective protection to reduce unnecessary power outages and enhance the reliability and safety of the power supply system.
