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.
Approved to MIL-PRF-83383.
