The Size S6 frame (172 mm high, 120 mm wide, 170 mm deep) determines panel cutout and rail spacing — the 170 mm depth matters when the enclosure door clearance is tight. Mounting is screw fixing, not DIN-rail snap-on, so plan for drilled backplate or mounting rail. The coil's spring-type terminals accept 2x (0.25-2.5 mm²) solid or stranded, which is standard for control wiring from a PLC output or relay. Switching frequency varies by duty: up to 800 cycles/hour in AC-1 (resistive), 750 in AC-3 (motor start/run), and 130 in AC-4 (plugging/inching). For a conveyor or pump motor on AC-3 duty, the 750 cycles/hour limit is the one that governs — don't exceed it in high-cycling applications like rapid reversing. Auxiliary switch is included, which saves ordering a separate block for status feedback to the PLC or indicator light. Arcing time 10-15 ms; opening time 40-60 ms on both AC and DC — consistent with standard contactor performance for coordination with upstream short-circuit protection. Minimum clearances: 10 mm upwards and downwards, 10 mm to the side, 20 mm forwards. The single 9 mm mounting hole (screw fixing) means a standard M8 bolt or equivalent through the backplate.","metaTitle":"Siemens 3RT1056-2AM36 SIRIUS Power Contactor, 200-220V Coil,","metaDescription":"Siemens SIRIUS 3RT1056-2AM36 power contactor, Size S6, 200-220V AC coil, spring-type terminals.
