Abstract

The thermal trip device of the multipole circuit-breaker (11) requires readjustment after the introduction of an auxiliary device such as a differential protection device (10) with an actuator (12) aligned with a receiver (13). Electrical coupling is provided by conductors (15) extending laterally from the base of the auxiliary with elbowed branches for connection to the circuit-breaker poles. Automatic readjustment is effected by a bar (17) with a return spring (19) and raised portions (17a-17d) which impinge upon the bimetallic strips (16a-16d) of the separate poles.
