Abstract

A contactor comprises a contact system arranged in a housing with a magnet ystem activating the contact system. The housing, at the end thereof remote from the side of the housing at which the housing is mounted in a switch box, is closed off by a cover. The contact system comprises contact bars with contact terminal screws and stationary contact pieces, and jointly activatable bridging members having movable contact pieces and operating as normally closed and/or normally open switches. The contact bars with their contact terminal screws are arranged displaced relative to one another in planes having differing spacings from the end of the housing at which the housing is mounted on a switch box, in such a manner that each contact terminal screw is freely accessible, even after all wiring has been connected on. This makes possible direct access to connections at the terminal screws of the more deep-lying planes, and makes it possible to wire on in sequences other than beginning with the plane closest to the mounting plane.

Dependent claims

A contactor, comprising, in combination, a housing having a mounting side for mounting the housing on a switchboard or the like, the housing being provided with a housing cover section at the side thereof remote from the mounting side, a contact system and a magnet system accommodated within the housing, the magnet system activating the contact system, the contact system comprising contact bars with contact terminal screws and stationary contact pieces and jointly activatable bridging members having movable contact pieces cooperating with the stationary contact pieces to form relay switches, the contact terminal screws comprising at least a first row of contact terminal screws located in a first plane parallel to and spaced a first distance from the mounting side of the housing and a second row of contact terminal screws located in a second plane parallel to and spaced a different second distance from the mounting side of the housing, the contact terminal screws of the first row, when viewed in the direction normal to the first and second planes, being offset relative to the contact terminal screws of the second row in the direction in which the first and second rows extend.
