Control and protection module of a switch device

A control and protection module for a low voltage multipolar switch device, designed to control and protect an electric charge, said switch device comprising a connector base fitted with current lines that have stationary and moving contacts, a control electromagnet and a trip device capable of acting on said moving contacts in order to open or break the power poles, the control and protection module comprising, in a housing attached in a detachable way to the connector base:

• current sensors which measure the strength of the current crossing said current lines,
• an electronic board that has a processing unit, and includes an electronic control device and an electronic protection device, responsible respectively for operating, by way of a control terminal block, the control electromagnet and the trip mechanism in response respectively to a control signal and a trip signal transmitted by the processing unit, wherein:
• the processing unit is configured to suppress the electromagnet control signal in the event of malfunction of the protection device.
