Multi-pole contactor-circuit breaker type switch has control and communication module removably fixed below protection module, to communicate processing circuit of protection module, through connectors

摘要

A control and communication module (3) removably fixed on the housing (1), below a protection module (2), communicates a processing circuit (22) of the protection module, through connectors (23). The control and communication module has state switches (31a,31b) mechanically activated by a control mechanism (14) and a pole control electromagnet (16) to provide state information about the poles and trip mechanism.
