The coil is 24 V at 50 Hz. Mounting is screw and snap-on onto 35 mm DIN rail per DIN EN 60715, with the mounting position allowing +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward. At 55 mm wide and 114 mm tall, this S2 contactor fits standard DIN-rail spacing. Spring-type terminals accept 2x (0.5 to 2.5 mm²) solid or stranded — no ferrule needed, which speeds panel wiring. The 10 mm clearance above and below, plus 6 mm side clearance, is the minimum for arc flash and heat dissipation; crowding it reduces the 1 200 1/h AC-1 switching rate. ## Duty Cycle and Switching Performance The contactor is rated for 1 200 operations per hour in AC-1 resistive duty, 1 000/h in AC-3 motor switching, and 300/h in AC-4 plugging/reversing. Operating time at AC is 10 to 18 ms, with arcing time of 10 to 20 ms — fast enough for most motor start/stop sequences but not for high-speed inching without derating. ## Environmental Range","metaTitle":"Siemens 3RT2035-3AB00-ZX95 SIRIUS Power Contactor, 55 mm","metaDescription":"Siemens SIRIUS 3RT2035-3AB00-ZX95 power contactor, size S2, 55 mm wide, 24 V 50 Hz coil, 480 V rated 40 A, spring-type terminals, DIN rail mount.
