The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, fitting into a compact 45 mm wide footprint with a depth of 73 mm and height of 58 mm. Rated for a main contact range of 20 to 12 A, the 3RT2015-1BW41 handles switching frequencies up to 1000 cycles per hour in AC-1 duty, 750 in AC-2 and AC-3, and 250 in AC-4. Mechanical life is typical 30 million operations. ## Sizing and Duty Class The headline rating here is the AC-3 switching current: 10 A at 24 V, 2 A at 48 V and 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. These numbers govern motor switching capability — the contactor is sized for small induction motors up to about 0.75 hp at 230 V. The AC-1 resistive rating is higher, but for motor loads the AC-3 figure is the one that decides fit. Wiring accepts solid 0.5 to 4 mm², stranded 0.5 to 4 mm², and fine-stranded 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².","metaTitle":"Siemens 3RT2015-1BW41 SIRIUS Power Contactor, Size S00, 48 V","metaDescription":"Siemens SIRIUS 3RT2015-1BW41 power contactor, size S00, 48 V DC coil, screw terminals.
