The Siemens 3RH1362-2AG10 is a SIRIUS auxiliary contactor in size S00, carrying six normally-open instantaneous contacts rated for AC-12 duty at 10 A maximum. It is designed to extend the signal-contact count on a contactor or motor starter — common in control panels where a single main contactor needs more auxiliary feedback or interlock paths than its built-in contacts provide. The 45 mm width and screw-and-snap-on mounting mean it clips directly onto a DIN rail alongside the main contactor, saving panel space vs. a terminal-block solution.
The AC-12 rating of 10 A covers resistive and solid-state loads at 24 V — the most common control-circuit voltage in industrial panels. At higher voltages the current drops: 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. If your circuit runs at 110 V, the contact is rated for 1 A. The 6 kV surge-voltage rating (impulse withstand) means it coordinates with standard IEC 60947-1 control-circuit isolation levels. Pollution degree 3 confirms it holds up in the conductive-dust environment typical of a panel near a production line, not just a clean room. That low-level reliability matters for PLC-input dry circuits — the silver alloy contacts handle the low energy without oxidation buildup.
The front face is IP20, so finger-safe once the panel door is closed but not rated for washdown. Shock resistance is 10g for 5 ms and 5g for 10 ms, covering most vibration from adjacent contactors or motor starters on the same rail. Wire termination accepts 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG).
