It carries a varistor surge suppressor built into the coil circuit — no separate suppressor module needed for basic transient protection. Main power terminals are spring-loaded, accepting 2x (0.25 to 2.5 mm²) solid or stranded conductors (2x 24–14 AWG). The contactor measures 45 mm wide by 60 mm high by 73 mm deep — fits a standard 45 mm DIN-rail slot with 6 mm side clearance for heat dissipation when mounted side-by-side. ## Switching Ratings by Duty Rated operational currents vary significantly by duty cycle and voltage. At AC-3 (squirrel-cage motors: starting, switching off running motors) the contactor delivers 5.5 kW at 400 V, 3.5 kW at 500 V, and 4 kW at 690 V. AC-4 duty (inching, plugging, reversing) at 400 V is rated 6.5 A. For resistive loads (AC-1 / AC-12) the maximum operating current is 10 A at 24 V and 6 A at 230 V. DC switching ratings: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. The coil draws 1.4 W closing and 1.4 W holding — a DC economizer is not required since holding power equals pick-up power. Type 1 coordination (no damage to contactor, but may need contact replacement) requires a 35 A gL/gG fuse.","metaTitle":"Siemens 3RT1015-2WB41 SIRIUS Power Contactor, 24 VDC Coil, S","metaDescription":"Siemens SIRIUS 3RT1015-2WB41 power contactor, Size S00, 24 VDC coil with varistor, spring-loaded terminals, IP20.
