Product details

Rated for 3 hp at 230 V AC and 10 A at 24 V DC, this contactor fits motor and resistive load applications where a compact 45 mm wide footprint is needed. It mounts on 35 mm DIN rail per EN 60715 with screw or snap-on fastening, and the mounting position allows ±180° rotation on vertical surfaces plus ±22.5° tilt forward/backward. Maximum switching frequency varies by duty: 1000 ops/h for AC-1 resistive loads, 750 ops/h for AC-3 motor starting, and 250 ops/h for AC-4 plugging/reversing. Arcing time is 10 ms, and dropout time on DC is 19 to 21 ms.

The S0 frame occupies 45 mm of DIN rail width, with 107 mm depth and 102 mm height. Main contacts accept 18 to 8 mm² conductors; dual terminals handle 2x (0.5 to 2.5 mm²) for control wiring. The contactor ships without an auxiliary switch block — plan for external auxiliaries if feedback signals are needed.
