Screw-type coil terminals and a built-in auxiliary switch with 1 NO + 1 NC configuration mean this contactor arrives ready for standard three-wire control schemes without an add-on block. ## DIN rail fit and clearance envelope The S2 footprint is 55 mm wide, 114 mm tall, and 130 mm deep — a standard three-module-wide slot on the rail. Side clearance to adjacent devices is 6 mm; top and bottom clearance is 10 mm each. ## Duty cycle and service life Maximum mechanical operating frequency varies by duty: 1,200 cycles/hour in AC-1 (resistive), 750 in AC-2 (slip-ring motor), 1,000 in AC-3 (squirrel-cage motor), and 300 in AC-4 (plugging/inching) (-,). For a motor-starting application running at 1,000 cycles/hour in AC-3, the contactor will reach its mechanical life after roughly 10,000 hours of continuous cycling — a data point for the maintenance planner scheduling contactor replacement intervals. Lifecycle stage is current production.","metaTitle":"Siemens 3RT2035-1NE30 SIRIUS Contactor, 48-80 V Coil, S2","metaDescription":"Siemens 3RT2035-1NE30 SIRIUS power contactor, size S2, 48-80 VAC/DC coil, screw terminals, auxiliary switch included.
