This contactor mounts via screw or snap-on onto a 35 mm DIN rail per DIN EN 60715, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward and backward. That flexibility simplifies panel layout when orientation is constrained by cable entry or busbar access. The S0 frame carries main contacts rated for AC-3 switching at up to 750 cycles per hour, with a mechanical life of 10 million operations typical. That cycle limit governs the contactor's suitability for high-duty applications like conveyor indexing or compressor cycling — not just continuous run. For resistive loads (AC-1) the maximum switching rate rises to 1 000 1/h, while heavy inrush (AC-4) drops to 250 1/h. Spring-type terminals on the coil accept solid or stranded wire from 1 to 10 mm², and up to 2x 0.5 to 2.5 mm² per clamp. No screw torque to verify — just strip to 8–10 mm and push in. That saves time during panel build and avoids loose-termination callbacks. The auxiliary contact block is built in, with a configuration of 1 NO + 1 NC (18... 8 in Siemens notation). Its DC breaking capacity is rated at 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V — so it handles PLC-level feedback signals but not high-DC loads without derating. Dimensions are 45 mm wide, 102 mm tall, 107 mm deep — the S0 footprint fits standard 45 mm pitch on DIN rail. These are the minimum air gaps to adjacent metalwork for arc flash containment; a panel builder should not crowd the contactor tighter than that without checking coordination with upstream protection. The arcing time is 10 ms per pole — fast enough to limit let-through energy in a fault scenario, but the upstream breaker's I²t curve should be verified for selectivity.","metaTitle":"Siemens SIRIUS 3RT2026-2BB40-ZW96 Power Contactor, S0, 24 VD","metaDescription":"Siemens SIRIUS 3RT2026-2BB40-ZW96 power contactor, S0 frame, 24 VDC coil, spring-type terminals.
