That coil voltage puts it squarely in the 600 V class panel — common in North American industrial mains where 480/600 V control transformers feed the contactor coil directly. The screw-type coil terminals and screw fixing mean it lands on a mounting plate, not a DIN rail; plan for four M11 bolts through the base holes. The main power circuit accepts stranded cable from 70 to 240 mm² — that's a heavy lug range, consistent with a contactor sized for motor loads in the 200-400 A ballpark. The auxiliary contact block is built in (auxiliary switch: yes), with ratings starting at 10 A at 24 V and tapering to 0.3 A at 220 V for the DC side. That matters if you're switching a PLC input or a small relay off the same block. Mounting position is flexible: vertical surface with ±90° rotation or ±22.5° tilt front-to-back. That covers most panel layouts, including top-entry gland plates. That covers unheated warehouses and most plant-floor environments.","metaTitle":"Siemens 3RT1466-6AT36 SIRIUS Contactor, Size S10, 575-600V","metaDescription":"Siemens SIRIUS 3RT1466-6AT36 contactor, Size S10, 575-600 V AC/DC coil, screw fixing, auxiliary contacts included, current lifecycle.

This 3RT1466-6AT36 uses a 575-600 V AC/DC coil with screw-type terminals; the 3RT1076-6AV36 may differ. They are not drop-in interchangeable without checking those two specs."},{"question":"What is the depth of 3RT1466-6AT36?","answer":"The depth is 202 mm. Overall dimensions are 210 mm height, 145 mm width, 202 mm depth."},{"question":"What wire sizes does the main power circuit accept?","answer":"The main power terminals accept stranded cable from 70 to 240 mm². The auxiliary control circuit terminals accept solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²)."},{"question":"Will 3RT1466-6AT36 drop into a panel specified around 3RT1076-6AV36?","answer":"Mechanically, both are Size S10 with screw fixing, so the mounting hole pattern and overall dimensions are the same. The electrical fit depends on coil voltage — this unit is 575-600 V AC/DC — and terminal type.
