Abstract

This contactor comprises a fixed circuit with three branches (5, 6, 7) cooperating with an armature (12) and energised by a coil supplied with DC, a housing (1) and a contact unit (2). At least one part of the cooperating pole surfaces (21, 21', 23, 23' - 22, 22', 24, 24') is inclined with respect to the axis of the central branch (7), whilst the outer limbs (5, 6) of the fixed circuit each have a lateral rim which bears on a corresponding stop (25, 25') placed in the vicinity of the bearing surface (11) of the housing (1) receiving the contact unit (2). Such a contactor is easy to assemble and the use of auxiliary contacts is possible, even for low values of the coil's supply voltage, without calling upon a bulky magnetic circuit and without requiring a number of ampere turns liable to cause excessive heating up of the coil. <IMAGE> [FR2406885A1]
