The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and its mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward — useful when panel layout forces an unconventional orientation. ## Ratings and Duty Cycles Switching frequency varies by duty: up to 1,000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor starting/running), and 250/h at AC-4 (plugging/inching). The AC-3e rating also supports 750/h. These limits govern thermal rise in the contactor — exceeding them in a high-duty application risks accelerated wear. The main contacts are rated for 20 to 12 A, and the contactor carries a typical mechanical life of 30,000,000 operations. Rated operational voltage is 220 V, with an initial value factor of 0.8 and a full-scale factor of 1.1. ## Wiring and Clearance Screw-type terminals accept solid or stranded wire from 0.5 to 4 mm², with dual-wire capacity: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². This covers common control wiring sizes for panel builders. These ensure adequate air gap for arc quenching and heat dissipation when multiple contactors are ganged on a DIN rail.","metaTitle":"Siemens 3RT2015-1BM41 SIRIUS Power Contactor, Size S00, 24 V","metaDescription":"Siemens 3RT2015-1BM41 SIRIUS power contactor, size S00, 24 VDC coil, screw terminals, 10 A at 24 VDC, 3 A at 400 VAC.
