Remote Control Circuit Breaker 4910 (RCCB)
Description
Technical data
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. Applying the system
voltage across the input will switch the RCCB ON, disconnection of the
input will cause it to switch OFF. Remote control is achieved through
the use of a conventional single pole manually operated aircraft style
thermal circuit breaker to connect the supply to the control input of the
RCCB. Complies with the requirements of MIL-C-83383.
4910 (RCCB)
Typical applications
Aircraft electrical systems and equipment, and other high performance
applications.
