The coil is spring-type terminals, rated at 500–550 V, with a pickup/dropout delay of 40–80 ms on both AC and DC. That 80 ms pickup window means the contactor isn't instant — factor it into your safety-circuit response time if you're sequencing multiple devices. Mounting is vertical surface with screw fixing; you can rotate ±90° or tilt ±22.5° front-to-back. Clearances: 10 mm above/below, 20 mm forward, 10 mm side — that's tight for a part this size, so confirm your enclosure depth against the 202 mm depth. ## Auxiliary contact ratings and switching frequencies This contactor includes an auxiliary switch. The auxiliary contacts are rated: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V. Those are resistive ratings — if you're switching inductive pilot loads, expect to derate or use a separate relay interface. Switching frequency depends on duty: 750 ops/h at AC-1 (resistive), 500 ops/h at AC-3 (squirrel-cage motor start/run), 250 ops/h at AC-2 (slip-ring motor), and 130 ops/h at AC-4 (plugging/inching). For a conveyor running continuous AC-3 duty, 500 ops/h is fine; for a jogging application, you're limited to 130 ops/h — don't exceed it or the arc chute wears fast. The 3RT5065-6AB36 is a different frame — the S10 frame here is rated for the heavy main-circuit cross-section (70–240 mm² stranded) and the 750 A AC-1 headroom. Dropping in a smaller-frame contactor without rewiring the power lugs isn't a straight swap; verify the lug capacity and short-circuit rating before changing order codes. ## Integration and mounting notes Screw fixing to a vertical mounting surface — no DIN rail adapter on this size. The 202 mm depth means a standard 300 mm deep enclosure leaves 98 mm for wiring and arc clearance. Four mounting holes, 11 mm diameter, one hole per corner. Solid or stranded auxiliary wiring: 2x 0.25–2.5 mm² per terminal. At 750 A AC-1, that arc energy is substantial — keep the side clearance of 10 mm clear of grounded metal and other devices. The 0.9 power factor at 50/60 Hz is the rated load PF; if your motor runs below 0.9, the contactor may see higher switching stress.","metaTitle":"Siemens 3RT1064-2AS36 SIRIUS Power Contactor S10, 750 A AC-1","metaDescription":"Siemens 3RT1064-2AS36 SIRIUS power contactor, size S10.
