    Product Detail
  Listing Description:1.Modular design, compact form, small volume, high reliability and zero arcing
2.Higher breaking capacity
3.With communication


Detailed Description: JECW65-630 series air circuit breaker (hereinafter referred to as breaker) is with Compact structure, small size, high reliability, zero arc and so on. It’s suitable for the circuit of AC 50Hz with rated voltage 400V, rated insulation voltage 690V. The rated current is 100~630A mainly used in Distribution network to distribute electric energy and protect circuits and power-supply equipment from overload, under-voltage, short-circuit and single-phase earth, with intelligent and selective protection functions with accurate action. The breaker can improve the reliability of power supply, and avoid unnecessary power failure.Under normal conditions, can also be used for Infrequent conversion of circuit, with isolation function.The breaker is applicable for power stations, factories, mines(for 690V) and modern high-buildings, especially for the distribution system of intelligent building.



This breaker conforms to IEC60947-2 and GB14048.2.
