Product details

At 45 mm wide, 102 mm high, and 144 mm deep, the S0 frame occupies a single DIN-rail module position.

Terminal and Wiring

Spring-type terminals accept solid or stranded conductors from 1 to 10 mm², with a solid or stranded option of 2x (0.5... 2.5 mm²). This spring-cage design eliminates the need for periodic screw-torque checks on the coil and main circuit connections.

The auxiliary switch (rated without auxiliary switch block) carries these make/break capacities at 24 V rated value: 6 A; at 48 V: 2 A; at 60 V: 2 A; at 110 V: 1 A; at 125 V: 0.9 A; at 220 V: 0.3 A; at 400 V: 3 A; at 440 V: 0.6 A. At 230 V the rating is 1 hp. These values govern the pilot-duty loads this contactor can switch directly.
