The S10 frame size gives you a solid 202 mm depth and 145 mm width, with a 210 mm height. That extra depth means you've got room for the arc chutes and auxiliary contact block without crowding the next device over. Mounting is flexible: you can rotate it ±90° on a vertical surface or tilt it ±22.5° front-to-back. That's handy when you're fitting it into a tight corner of an existing panel and the bus bars don't line up square. The DC coil operates on 110 V DC with a pick-up time of 80 to 100 ms and an arcing time of 10 to 15 ms. That's a fast, clean break — important when you're switching inductive loads like motor starters that can kick back a voltage spike. ## Wiring and conductor sizing That covers the control wiring range for most auxiliary circuits, but for the main power legs you'll need lugs or a bus bar — the terminals are sized for the control side, not the 156 A main path. That's tight enough to stack contactors in a multi-motor panel, but leave that forward clearance for arc-flash safety and access to the auxiliary switch. ## Environmental tolerance That's a wide enough swing for unheated warehouses or outdoor cabinets in a northern climate. The contactor doesn't care about the cold — it's the coil seals and plastic housing that hold up. That saves a DIN rail slot and a wiring step.","metaTitle":"Siemens 3RT1466-2XF46-0LA2 SIRIUS Contactor, S10, 156 A at 4","metaDescription":"Siemens 3RT1466-2XF46-0LA2 SIRIUS S10 contactor, 156 A at 480 V AC.
