Structure teatures
This series earth leakage circuit breakers are breaker: with electronic current protection. The main components include main switch (containing overeurreut trip), zero sequence current mutual inductor, electronic amplification part, earth leakage trip, test device and other parts. All these ;hall be fitted in a plastic shell The specification for the outline volume ofFCMlLearth leakage circuit breaker is the same as that ofFCM1 molded case breaker. So they have the interchangeability for the installation.And t- be ensured when the voltage is reduced to SOV. The breaker has the function of alarm output for earth leakage
Please refer to Table 3 and Table 4 for main technical uerformance index of the breaker
Internal fittings
.Internalntongs of circuit breaker The connection wire of breaker t7ttings can be led out directly if required by the client, or connection terminal oPthe lead can be added .Please refer to Table 7 for the power ofundervoltage trip Undervoltage trip should ensure the trip ofcircuit breaker at the conditi< n of 35 }-70% of rated operation voltage, and the breaker can be closed or re-tripped only when undervoltage trip is powered, otherwise the switch may be damaged .Wiring dia__ram (internal fittin__s of the switch in dotted box) |
