TSW8 Intelligent Circuit Breaker

Basic Information

Product Description


TSW8 series intelligent circuit breaker is suitable for the circuit of AC 50/60Hz with rated voltage 400V, 690V and rated current up to 6300A. It is mainly used for distribution electric energy as well as protecting circuit and power supply equipment from overload, under-voltage, short-circuit and single phase earthing. With intelligent and selective protection functions, the breaker can improve the reliability of power supply, and avoid unnecessary power failure. The breaker is applied to power stations, factories, mines (for 690V) and modern high-building, especially to the distribution system of intelligent building. The breakers comply to IEC60947-2.
