Product details

Its main contacts are rated for 16 A to 8 A (AC-3 duty), and it handles up to 1,000 switching cycles per hour under AC-1, AC-2, and AC-3 loads, dropping to 300 cycles per hour under AC-4 duty for demanding inching or plugging applications. The 24 VDC coil draws 6 A at rated voltage, with a pick-up threshold of 0.8 x rated value and a drop-out of 1.1 x rated value, giving a clear operating margin for control circuits. Snap it onto a 35 mm DIN rail per DIN EN 60715 or screw-mount it; the mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt, which helps when fitting into tight panel layouts.

The S0 frame measures 45 mm wide, 85 mm tall, and 151 mm deep, so it occupies a single 45 mm DIN-rail slot — plan for that footprint when laying out the panel. Wire the main circuit with solid or stranded conductors from 1 to 10 mm²; auxiliary circuits accept two conductors per clamp, from 0.5 to 1.5 mm² (solid or stranded) or 0.75 to 2.5 mm².
