Abstract
This invention relates to a multi-pole contactor—circuit breaker type switch composed of a housing (1) containing breaking poles (11) activated by a control electromagnet (16) and by a trip control mechanism (18, 14) and comprising a protection module (2) equipped with means (21) for measuring pole currents and means (22) for acting on the electromagnet (16) and on the trip control mechanism (14) if a fault current is detected, characterised by the fact that it comprises a control and/or communication module (3) that is installed removably on the housing, below the protection module (2) and communicating with the processing circuit (22) on the said protection module (2) through connectors (23, 33).
