Product details

It accepts a universal AC/DC coil rated 175-280 V, with screw-type terminals for the magnet coil and main/auxiliary contacts. Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with flexible positioning: +/-180° rotation on vertical surfaces and +/-22.5° tilt forward/backward. The S2 frame (75 mm wide, 114 mm tall, 130 mm deep) fits standard panel layouts with 10 mm clearance above/below and 6 mm at the sides.

Coil and Switching Characteristics

The universal AC/DC coil operates across 175-280 V, with a pickup threshold of 0.8x rated and a dropout of 0.3x rated. The coil is screw-terminal type, accepting 2x (0.5-1.5 mm²) solid or 2x (0.75-2.5 mm²) stranded conductors. Auxiliary contacts are included (18-1 configuration for main contacts). Rated switching capacities at various voltages: 10 A at 24 V, 2 A at 48 V, 6 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 10 A at 230 V, and 3 A at 400 V.
