The contactor carries an auxiliary switch and is rated for main contact switching at 20–12 A. ## Wiring and conductor range The spring-type terminals eliminate the need for screwdriver torque checks — strip, insert, done. This matches typical panel-building practice for control circuits up to 4 mm². ## Switching performance and operating rates Operating rates vary by duty: 1,000 cycles/hour at AC-1, 750 cycles/hour at AC-2, AC-3, and AC-3e, and 250 cycles/hour at AC-4. DC switching time is 7–13 ms. The coil hold-in factor is rated at 0.8 initial, 1.1 full-scale. These figures matter for high-cycle applications like conveyor or pump cycling — AC-4 rate limits plugging and inching duty. The auxiliary switch is rated for switching at various control voltages: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. At 230 V it carries a 0.75 hp motor rating. These are the numbers to check when the auxiliary feeds a PLC input or another contactor coil.","metaTitle":"Siemens 3RT2015-2UB41 SIRIUS Power Contactor, 24 VDC, S00","metaDescription":"Siemens SIRIUS 3RT2015-2UB41 power contactor, 24 VDC coil, size S00, spring-type terminals, 45 mm wide.
