The Siemens 3RH1131-1AV60 is a SIRIUS auxiliary contactor in size S00, carrying three normally-open instantaneous contacts rated for 10 A at AC-12 duty. That AC-12 rating means it's specified for resistive loads at line voltage — the contactor handles the steady-state current without the inrush a motor or solenoid would draw. The 6 kV surge voltage resistance gives it a solid margin for industrial panel environments where switching transients are common.
Panel integration and mounting
Mounting is via screw or snap-on onto a DIN rail, per the fastening method. The footprint is 45 mm wide by 57.5 mm tall by 72 mm deep — a standard S00 envelope that fits alongside contactors in the same frame size. The mounting position is flexible: ±180° rotation on a vertical surface, and ±22.5° tilt forward/backward. That matters when you're fitting this into a crowded gland plate area or a swing-frame panel where the rail isn't perfectly vertical. Terminals accept solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm². For AWG, that's 2x 20–16, 2x 18–14, or 1x 12. The IP20 front protection means it's touch-safe on the front face once installed in a panel — standard for control cabinets where the door provides the environmental seal.
Contact ratings and switching capability
The three instantaneous contacts are rated across a range of voltages. At 24 V the contact carries 10 A; at 230 V it's 6 A; at 400 V it's 3 A; at 690 V it's 1 A. The 60 Hz rated voltage is 480 V. These are the make-and-break ratings for the contact set — use the AC-12 10 A figure as the headline resistive load limit, and derate per the voltage curve for your specific line voltage. Contact reliability is specified as one incorrect switching operation per 100 million operations at 17 V, 1 mA — that's the low-energy switching floor, relevant for PLC-level signals.
Environmental and mechanical endurance
Operating temperature range is -25 to +60 °C; storage and transport range is -55 to +80 °C. Shock resistance is 10g for 5 ms and 5g for 10 ms. Mechanical endurance for the contactor is 30 million operations typical. Pollution degree 3 means it's rated for conductive pollution or dry non-conductive pollution that becomes conductive due to condensation — typical for industrial control panels not in a cleanroom.
