The auxiliary contact ratings drop with voltage: 6 A at 24 V DC, 2 A at 48 V and 60 V DC, 1 A at 110 V DC, and 0.9 A at 125 V DC. That means the auxiliary circuit's current capability is highest at the coil voltage; if you're switching a 125 V DC pilot light, you're limited to 0.9 A. The screw terminals accept 2x (0.25 to 2.5 mm²) solid or stranded — standard for control wiring up to 14 AWG.","metaTitle":"Siemens 3RT1075-2XB46-0LA2 SIRIUS Contactor, S12, 24 V DC Co","metaDescription":"Siemens SIRIUS contactor 3RT1075-2XB46-0LA2, size S12, 24 V DC coil, screw fixing.
