Keep 10 mm clearance at the sides, 10 mm upward, 20 mm forward, and 10 mm downward for arc venting and heat dissipation. ## Coil and control circuit — what the ratings mean The coil pulls 0.4 A at 50 Hz and 0.4 A at 60 Hz at the rated 200... 277 V. Pickup and dropout timing is 80... 100 ms on both AC and DC supplies, and arcing time runs 10... 15 ms. The coil hold-in range starts at 0.8 × rated voltage (160 V minimum) and the full-scale overvoltage limit is 1.1 × rated (305 V). That 0.8 initial value means the contactor stays pulled in through a moderate brownout — useful if you're on a shared distribution with motor-start dips. Auxiliary switch contacts are built in, rated at 10 A at 24 V, 2 A at 48 V and 60 V, and 1 A at 110 V — enough for PLC input sensing or relay interlocking without an add-on block. ## Switching duty and mechanical life Maximum operating frequency varies by duty: 500 cycles/hour in AC-1 (resistive), 420 in AC-3 (squirrel-cage motor starting), 420 in AC-3e (enhanced motor), 170 in AC-2 (slip-ring motor), and 130 in AC-4 (plugging/inching). ## Wiring and termination details The coil uses screw-type terminals accepting 2 × (0.5... 1.5 mm²) solid or 2 × (0.75... 2.5 mm²) stranded, max 2 × (0.75... 4 mm²). Main power terminals take 70... 240 mm² stranded — that's a serious lug range, typically 2/0 to 500 MCM in AWG terms, for high-current motor circuits or feeder taps. One mounting hole per terminal, 11 mm diameter, for standard M10 hardware. ## Environmental limits","metaTitle":"Siemens 3RT1076-6NP36 SIRIUS Power Contactor, Size S12, 200-","metaDescription":"Siemens SIRIUS 3RT1076-6NP36 power contactor, size S12, 200-277V AC coil, screw terminals.
