Product details

Auxiliary contactor for control-circuit switching

Its 10 A rating at 24 V covers typical PLC and relay coil loads; derate to 6 A at 230 V and 3 A at 400 V for higher-voltage control circuits.

Pollution degree 3 rating confirms it tolerates conductive dust and humidity typical of industrial control rooms.

Contact ratings and reliability

Three instantaneous NO contacts rated for AC-15 and DC-13 switching. At 24 V the contact carries 10 A; at 110 V it drops to 1 A; at 220 V to 0.27 A; at 230 V to 6 A; at 400 V to 3 A; at 500 V to 2 A; at 690 V to 1 A. Surge voltage resistance is 6 kV, adequate for 400 V control circuits with proper surge suppression.

Environmental limits

Shock resistance rated at 10 g for 5 ms and 5 g for 10 ms, covering most industrial vibration profiles without contact chatter.

Frequently asked questions

How do I get current pricing and availability for 3RH1131-2AH00?

Current pricing and availability are confirmed at quote time against an RFQ through independent distribution; submit an inquiry for a firm quote.

Will 3RH1131-2AH00 drop into a panel specified around 3RH2131-2AK60 without rewiring?

The 3RH1131-2AH00 shares the same size S00 footprint and screw/snap-on mounting as the 3RH2131-2AK60, but the 3RH2131-2AK60 carries different contact configurations — verify your contact count and voltage ratings before substituting.

What compliance documentation does Siemens provide for 3RH1131-2AH00?

Siemens provides RoHS/REACH compliance documentation and a declaration of conformity to IEC 60947-5-1 for the SIRIUS 3RH1131-2AH00.
