SONTUOEC ST45 3P/4P ACB 1600A Vacuum Circuit Breaker Fixed Intelligent Air Circuit Breaker
General
ST45 series DW45 universal circuit breaker(hereinafter referred to as
breaker)is suitable
for the circuit of AC 50Hz with rated voltage 400V, 690V and rated
current up to 6300A.
It is mainly used to distribute electric energy and protect
circuits and power-supply
equipment from overload, under-voltage, short-circuit and
single-phase earthing. with
intelligentized and selective protection functions, the breaker can
improve the reliability
of power supply, and avoid unnecessary power failure. The breaker
is applicable for
power stations, factories, mines(for 690V) and modern
high-buildings, especially for the
distribution system of intelligentized building. This breaker
conforms to IEC60947-2 and
