New Type MCCB YCM9LZ Earth Leakage Circuit Breaker
Product Overview
YCM9LZ series residual current operation circuit breaker(shortened as auto reclosing) is a newly-developed new-generation integrative multi-functional product which adopts patent technology and conforms to all intelligent requirements of state grid administration. It's the priority product to cooperate with China National Grid. It is equipped with functions of short-circuit, over-current, residual current, phase failure, off zero and special wave; Apart from these, we also have residual current display, real-time load current display, phase voltage display, on-off indication, time display and fault inquiry; What's more, it has functions of auto-reclosing after residual current operation circuit breaker acts when residual current, under-voltage, overvoltage, phase failure happens. It is used in power distribution circuit of AC 50Hz rated insulation voltage 800V(690V for 100A frame current), rated voltage 380/400V,
Rated current 40A-630A to distribute energy and protect circuit line.
It is widely used in three phase four wire neutral point directly grounded(TT system) LV grid to provide indirect contact protection against personal electric shock hazard and also is used to protect against grounding fault, over-current and short circuit of circuit or equipments.
It is widely installed at vacant facilities such as city grid, metering box and LV IP cabinet(integrated meter box of power transformer) of transformation of rural power network, rebroadcasting station on mountains, base station; Independent facilities, power cabinet, and distribution board for traffic light system. When the circuit breaker trips because of Temporary earth leakage or instantaneous earth leakage or voltage fault caused by electric surge, the power can be restored directly through self re-closing function without manual operation. The circuit breaker can be installed vertically as well as horizontally.
