40a 4p 30ma rccb

Specifications

Pole:2P, 4P
Rated Current:16~100A
Rated Leakage Current:30MA;100MA;300MA
Type:Magnetic / Electric type RCCB

Residual current circuit breaker RCCB,RCD

240V single phase, 415V three phases and below it for industrial and mining enterprise,
trade building, commerce and family. To mainly prevent electric fire and personal
casual-ty accident caused by personal electric shock or leakage of electrified wire netting,
this ELCB is a current-operated, fast leakage protector of pure electromagnetic type,
wh-ich can break off fault circuit rapidly in order to avoid occurrence of accident.
The item is precise in structure, less elements, without auxiliary power and high
working reliability. The function of the switch won`t be influenced by ambient temperature
and lightning. The mutual inductor of the item is used to test vector differential
value of passing current, and produces a relevant output power and add it to the tripper
insecondary winding, if the current of vector differential value of protected circuit
of personal electric shock is up to or over leakage operating current, the tripper will
act and cut off so that the item will take effect of protection.

 

Feature

Provides protection against earth fault/leakage current and function of isolation
High breaking current withstand capacity
Contact position indication
Equipped with finger protected connection terminals
Fire resistant plastic parts endures abnormal heating and strong impact
Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity
Independent of power supply and line voltage, and free from external interference, voltage fluctuation
