Rated at 5.5 kW at 400 V in AC-2 and AC-3 duty, it handles motor starts and stops on pumps, fans, and compressors within that power band. AC-4 at 400 V is rated 8.5 A for reversing or jogging applications where the contactor breaks full-load current on every cycle. Auxiliary contacts — 1 N/O + 1 N/C — are rated 10 A at 24 V, tapering to 0.3 A at 220 V DC. That 10 A at 24 V is your PLC output interface; the 0.3 A at 220 V is for pilot-duty control circuits. At 45 mm wide, 57.5 mm tall, and 72 mm deep, this S00 contactor eats minimal DIN rail space. Side-by-side mounting is allowed — no gap between units — but if you're packing them tight, remember the 6 mm side clearance to grounded metal for the arc chamber. Front face carries an IP20 rating — safe for finger-probe access inside an enclosure. Pick-up voltage is 0.85 x nominal (20.4 V for a 24 V coil); drop-out is 1.1 x nominal (26.4 V). That 85% pick-up means a sagging DC bus won't drop the contactor prematurely, but it also means you need a clean 24 V supply. The holding power being the same as closing — 3.3 W — tells you it's a DC-operated economized coil, not a simple solenoid. Mechanical life is rated 30 million operations — that's a lot of cycles for a conveyor line or a pump start.","metaTitle":"Siemens SIRIUS 3RT1017-1BB42-ZW97 Power Contactor, S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1017-1BB42-ZW97 power contactor, frame size S00, 24 VDC coil, 5.5 kW at 400 V AC-2/AC-3.
