Intelligent universal circuit breaker TEW1 |
TEW1 series intelligent universal
circuit breaker (hereinafter referred to as
breaker) is suitable for AC 50HZ power distribution
network with a rated voltage up to 600W (690V),
rated current of 630A-6300A, it is used for
power distribution and protection of circuit
power supply from damages by such problems as
overload, under voltage, short circuit, single-phase
grounding etc. This circuit breaker has intelligent
protection function, for precise selective protection,
can improve power supply reliability, to avoid
unnecessary power outages. At the same time,
