Product details

Switching capacity and contact ratings

Rated for AC-12 duty at 10 A at 24 V, and 6 A at 230 V. These ratings cover the typical control-circuit loads — relay coils, contactor coils, pilot lights, and PLC digital inputs — across the common voltage levels in industrial panels. The contacts are rated for 10 million mechanical operations typical, matching the service life of the contactor it follows.
