It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a ±180° rotation range on vertical surfaces and ±22.5° tilt allowance — useful when panel layout forces an unconventional orientation. The coil connection uses spring-type terminals, so no screwdriver is needed for the control wiring — just strip and push. Main contacts are configured as 18 normally-open, 1 normally-closed (18 NO / 1 NC), which covers most three-phase motor circuits with an auxiliary NC for interlocking or status feedback. ## Duty-cycle and switching frequency limits Maximum switching frequency depends on the duty class: 1,000 cycles/hour in AC-1 (resistive), 800 in AC-3 and AC-3e (motor starting/running), 600 in AC-2 (slip-ring motor), and 250 in AC-4 (plugging/inching). If your application cycles faster than these limits, you'll need to step up to a larger frame or reduce the load current. ## Environmental and mounting clearances These matter for heat dissipation and arc-flash containment — don't crowd it against other components. Dimensions are 114 mm high, 75 mm wide, 130 mm deep. The 75 mm width is three 25 mm module spaces on a DIN rail, so it occupies three standard positions. ## Auxiliary contact ratings across voltages The auxiliary contacts (no auxiliary switch block included as standard — this is the base contactor) are rated for the following currents at various control voltages: 6 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.6 A at 440 V, and 2 A at 500 V. These are the make/break capacities for the built-in auxiliary circuit; if you need more auxiliary contacts, add a separate auxiliary switch block.","metaTitle":"Siemens 3RT2036-3AF06 SIRIUS Power Contactor, Size S2, 52 A","metaDescription":"Siemens 3RT2036-3AF06 SIRIUS power contactor, Size S2, rated 52 A at 480 V.
