Product details

Auxiliary contactor for SIRIUS S00 contactors

It carries a 60 V DC coil drawing 3.2 W closing and holding power, with 3 normally open and 1 normally closed instantaneous contacts. Front IP20 protection keeps panel builders safe during commissioning.

Contact ratings and switching reliability

Rated operational current varies by voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V (–).

Terminal wiring accepts 2x (0.25... 2.5 mm²) solid or 2x (24... 14) AWG stranded. Shock resistance is 10g / 5 ms and 5g / 10 ms.

Frequently asked questions

What is the closest functional second-source for 3RH1131-2BE40?

The closest functional peer is 3RH2122-1BW40, which shares the S00 size and auxiliary contact function but differs in coil voltage and contact configuration. Verify coil voltage and contact count before substituting.

Will 3RH1131-2BE40 drop into a panel specified for 3RH2122-1BW40?

Both are S00 size with the same 45 mm width and snap-on DIN mounting, so mechanical fit is identical. The deciding factor is the coil voltage: 3RH1131-2BE40 uses 60 V DC, while 3RH2122-1BW40 uses a different coil. Check the control circuit voltage before swapping.

Where can I buy 3RH1131-2BE40?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.

What compliance documentation does Siemens provide for 3RH1131-2BE40?

RoHS compliance is documented with a substance prohibition date of July 1, 2006. The part carries IP20 front protection and is rated for pollution degree 3. Standard Siemens declarations for CE, UKCA, and EAC are available upon request.
