Remote Control Circuit Breaker 4930 (RCCB)

Description

Single pole remote control circuit breaker (RCCB), temperature

compensated, either with or without auxiliary contacts, and featuring

a bimetal actuator which trips the circuit breaker mechanism within

a specified time under overcurrent conditions. The switching contact

latching system is operated by a bi-stable linear motor controlled by

electronic circuitry incorporated within the device. Remote control

is achieved through the use of a conventional single pole manually

operated aircraft style thermal circuit breaker type 4120-0,5 A which

connects the control input of the RCCB to ground.

With the control circuit breaker (ICU) in the ON position, the RCCB will

switch on. When the control circuit breaker is switched off, the RCCB

will change to the OFF condition. If power is applied to a previously

de-energised RCCB, the device will adopt the same switching status

as the control circuit breaker.

If the RCCB trips thermally in the event of a load circuit fault, the

electronic circuitry will also cause the control circuit breaker to trip,

thereby providing a visual indication through the position of the circuit

breaker actuator.
