Product details

It is rated for 10 A at 24 V, with a 50/60 Hz coil tolerance of 0.8–1.1 × rated voltage at 50 Hz and 0.85–1.1 at 60 Hz.

The 10 A AC-12 rating at 24 V governs the contactor's ability to switch resistive control loads at that voltage — a typical PLC output or relay coil circuit. The four instantaneous contacts (no delayed or leading/lagging action) make this a straightforward auxiliary block for extending a contactor's signal circuit, not for timed or sequenced switching. Pollution degree 3 rating confirms suitability for industrial atmospheres with conductive contamination.

Screw or snap-on mounting to DIN rail. Zero side clearance required. Shock resistance rated at 10g / 5 ms and 5g / 10 ms, covering most industrial vibration profiles.
