The screw-type magnet coil terminals and the built-in auxiliary switch mean this is a 'fit and wire' part for a panel builder — no extra modules to order for basic signaling. ## Mounting and panel fit — the DIN rail reality The S2 footprint is 75 mm wide, 114 mm tall, and 130 mm deep — that's the depth you need to budget for gland-plate clearance behind the rail. That zero forward clearance means you can butt the contactor against a back panel or another device without derating — useful when packing a dense row. The coil pulls 25 A inrush peak, then holds at the rated 175-280 VAC range. Pickup dropout time is 30-55 ms AC or DC; arcing time runs 10-20 ms. The auxiliary switch is rated for switching: 10 A at 24 V, 2 A at 48 V or 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 440 V. That's a wide voltage spread — the 6 A at 230 V covers most European control circuits, while the 0.3 A at 220 V handles lower-power signaling. The 10 A at 24 V is your DC interlock or PLC input workhorse. Wire capacity on the aux terminals: 2x 0.5-1.5 mm² solid or 2x 0.75-2.5 mm² stranded — standard for control wiring. ## Operating environment and mechanical endurance That -40 °C low end means it's fine in unheated enclosures or cold storage areas — no heater needed for startup. Maximum switching rate at AC-1 is 350 operations per hour — enough for most conveyor or pump cycling, but not for high-speed pick-and-place.","metaTitle":"Siemens 3RT2536-1NP30 SIRIUS Contactor, S2 Size, 175-280 VAC","metaDescription":"Siemens 3RT2536-1NP30 SIRIUS contactor, size S2, 175-280 VAC coil.
