RDM5E series Electronic molded case circuit breaker with CE

RDM5E series Electronic MCCB is applied to power distribution network of AC50/60Hz, Rated operate voltage up to 690, Rated current up to 800A.t ismainly used to distributing electric energy and protecting circuit and power-supply device against the faults of overload, shor-circuit and under-voltage.And it also can works for transfering circuit and starting motor unfrequently. MCCB has protect functions of overload longtime-delay inverse timeimit, shor-circuit shor-ime delay inverse time limit, short-circuit shor-time constant time-ag, shor-circuit instantaneous and undervoltage. This producihas advantages of small volume, high breaking capacity, short-arc, accessory easy install, anti-vibration.This product conforms to standard of IEC60497-21

Remarks:

1) It has overload thermal memory function: overload thermal memory function, short circuit (short time delay) thermal memory function. 2) Communication function: standard RS485 interface, Modbus field bus protocol. It is realized through plug-in accessories. See the following table for the configuration of communication accessories:

No	Description			Accessory function
1	Communication shunt alarm accessories			Communication+shunt+overload alarm without tripping+reset button+work indication
2	Status feedback communication attachment			Four remote communication+reset button+work indication
3	Prepayment attachment			Prepayment control+work instructions
