Screw fixing through an 11 mm hole is the mounting method — no DIN rail clip on this variant, so budget panel drilling and a screwdriver during installation. Mounting position is flexible: vertical surface with ±90° rotation and ±22.5° tilt front-to-back, which helps when the contactor sits in a crowded sub-panel or on a swing frame. The coil is rated 220–240 V AC, screw-type terminals, and the contactor carries a built-in auxiliary switch — no separate add-on block needed for basic feedback. ## Duty-cycle limits — what the switching frequencies tell you Maximum switching rate is duty-class dependent: 500 operations/hour in AC-1 (resistive), 420/h in AC-3 (squirrel-cage motor start/run), 170/h in AC-2 (slip-ring motor), and 130/h in AC-4 (plugging/inching). The AC-3e rating matches the AC-3 figure at 420 ops/h, confirming the contactor is optimised for standard motor starting duty rather than high-cycle inching. Arcing time is 10–15 ms, and operating times (both AC and DC coil) are 60–100 ms — consistent with a general-purpose power contactor, not a fast-transfer switch. ## Wiring and thermal envelope Main power circuit accepts stranded conductors from 70 up to 240 mm² — this is a heavy-current contactor, sized for large motor feeders or busbar tap-offs. Auxiliary/control circuit wiring accepts 2x (0.5–1.5 mm²) solid or 2x (0.75–2.5 mm²) stranded, with a max of 2x (0.75–4 mm²) — covers standard control wiring up to 4 mm². Operating ambient is -25 to +60 °C, storage -55 to +80 °C — fine for most indoor panel environments, but check the derating if the panel internal temperature exceeds 60 °C. Clearance distances are tight: 10 mm upwards/downwards/sideways, 20 mm forwards — plan the panel layout so adjacent components or cable ducts don't crowd these gaps. ## Auxiliary contact ratings and mechanical life The built-in auxiliary switch is rated 10 A at 24 V, 2 A at 48 V or 60 V, and 1 A at 110 V — sufficient for signalling to a PLC input or a pilot light, but not for driving a large contactor coil directly at higher voltages. Mechanical endurance is 10 million operations typical — the contactor itself will outlast most application lifetimes before the mechanism wears, assuming the electrical load stays within the duty-cycle limits.","metaTitle":"Siemens 3RT1076-6AP36-3PA0 SIRIUS Power Contactor, Size S12","metaDescription":"Siemens 3RT1076-6AP36-3PA0 SIRIUS power contactor, Size S12, 220-240 V AC coil, screw terminals, screw fixing.
