Patent ID: 8115578

Claim:
An electromechanical relay, comprising: a case having a plurality of terminals with wiring fixed to said plurality of terminals from a circuit to be protected, each terminal of said plurality of terminals having a connector and a relay module capable of being received in said case, said relay module comprising cooperating connector means so that electrical contact between corresponding connectors on said case and on said relay module are electrically connected when said relay module is located within said case, wherein said corresponding connectors on said relay module each having a fixed contact for said relay module: a movable contact associated with each said fixed contact operable by an armature on said relay module, said armature being associated with a relay coil, so that upon a required current passing through said relay coil, said armature and an associated said movable contact will be moved for making, or breaking, a connection with the associated said movable contact; and, a double-make or double-break arrangement of contacts for increasing isolation between an open said movable contact and increasing a current break-rating.
