Abstract

1. Two-phase differential circuit breaker for a low-voltage alternating current network with a moulded insulating housing (12) comprising : - a differential transformer (82) with a ring core comprising primary windings constituted by phase and neutral conductors of the network, and a secondary winding generating a trip signal when an earth fault appears, - a contact system (86) to interrup the phase and neutral circuit in the open position of the contacts, - an actuating mechanism (42) of the contacts, comprising a lever (40) for manual operation and an automatic trip device when a faut occurs, - a control relay (72) of the trip device actuated by the trip signal of the secondary winding of the differential transformer and associated to the lock (78) of the mechanism (42), - and a pair of connection terminals (22, 24) per pole, characterized by the fact that the actuating mechanism (42) is arranged between a first and a second stationary plate (56, 58) extending in the same time parallelly to the lengthwise aligned direction of the terminals (22, 24) of each pole and perpendicularly to the front side of the housing (12), the first plate (56) constituting the main support of the self-bearing structure of the electromechanic assembly (20), and that the contact system (86) and the differential transformer (82) are arranged on the same side of said first palte (56), and on different levels according to the direction perpendicular to the front side, the actuating mechanism (42) and the trip relay (72) being respectively crosswise juxtaposed with the contact system (86) of the upper lever, and with the differential transformer (82) of the lower level.
