Termination is via spring-loaded terminals on the main current circuit, accepting 2x (0.25 to 2.5 mm²) solid or stranded wire — no screw torque, no re-tightening during thermal cycling. The contactor carries an integrated varistor surge suppressor across the coil, meaning you don't need to add a separate RC snubber for DC switching — the coil's closing and holding power both sit at 1.4 W DC, a steady draw that keeps the control transformer sizing predictable. If your application cycles the motor on and off under full load (conveyor jog, crane inching), this is the number that governs contact life, not the AC-12 figure. Mechanical life is typical 30 million operations — that's the bare contactor without load. Electrical life will be lower and depends on the switching category and current; the AC-4 rating is where you'll see the shortest contact endurance.","metaTitle":"Siemens SIRIUS 3RT1016-2WB42 Power Contactor, S00, 24 VDC, 1","metaDescription":"Siemens SIRIUS 3RT1016-2WB42 power contactor, size S00, 24 VDC coil, 10 A AC-12 rated.
