Product Description

SONTUOEC JZW-2000/3  3P/4P ACB 1600A Vacuum Circuit Breaker Fixed Intelligent Air Circuit Breaker
General
JZW-2000/3 series JZW-2000/3 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
GB14048.2. The whole series have past CCC certification.
