Product Introduction
MW1 Series of intelligent frame circuit breaker (hereinafter referred to as circuit breaker), suitable for ac 50HZ, rated working voltage to 1000V and below, rated working current 400a-6300a power distribution network, used to allocate electrical energy to protect the line and power equipment from overload, short circuit, undervoltage, single-phase grounding and other hazards.
With intelligent 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.
Operation conditions
