The arrangement for mechanically coupling an overload relay (1) to a contactor (2, 15) is suitable for use with a contactor (2) having connection terminals (11) with wire cages (17) as well as with a contactor (15) having connection terminals (16) with pressure plate claws (12). In order to allow mechanical coupling for both types of connection terminals (11, 16), the coupling cutout in the base of the contactor (2, 15) contains a central cutout (7) and two slots (8, 9) on both sides of the central cutout (7), which are aligned in the pick-up direction of the connection terminals (11, 16). The central cutout (7) is provided to accept the entire end section of the hook (3), and both the slots (8, 9) accept only the flat end section (4) that lies behind the latch element (5) of the hook (3). Depending on the type of connection terminal of the contactor (2, 15), the latch element (5) locks behind the rim defined by either the lower slot (9) or the upper slot (8), because the overload relay (1) and therefore the latch element (5) is pushed down when connecting to terminals (11) with pressure plate claws (12), and is pulled up when connecting to terminals (16) with wire cages (17).
