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 1 de-energised RCCB, the device will adopt the same switching status as the control circuit breaker. 4930 (RCCB) 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 (T = 25 °C, U = DC 28 V or AC 115V/400 Hz) Technical data A e breaker actuator.
