SIRIUS S00 power contactor — 24 VDC coil, spring terminals
The Siemens 3RT2015-2BB42-ZW97 is a SIRIUS-brand power contactor in the compact S00 frame size, built for switching motor loads and resistive circuits in control panels. It snaps onto a 35 mm DIN rail per DIN EN 60715 and accepts spring-type terminals for the coil and main contacts — no screwdriver needed for termination, which speeds panel wiring and reduces loose-connection callbacks. The coil is rated 24 V DC, and the contactor carries a DC-13 switching capacity of 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. For AC motor duty (AC-3), the contactor is rated for 750 switching operations per hour; for resistive loads (AC-1), it handles up to 1 000 cycles per hour. The arcing time falls between 10 and 15 ms, and the DC switching delay is 7 to 13 ms. Operational temperature range is -25 to +60 °C, with storage from -55 to +80 °C. The contactor includes an auxiliary switch and main contacts rated 20 to 12 A. Mechanical life is typically 30 000 000 operations. Mounting position is flexible: ±180° rotation on a vertical surface, and can be tilted forward/backward by ±22.5°. Clearance requirements are tight: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm at the side. Conductor cross-section accepts 0.5 to 4 mm² solid or stranded, and 2x (0.5 to 4 mm²) for double ferrule. Dimensions are 70 mm height, 45 mm width, and 73 mm depth.
