Product details

The coil is rated for AC control supply voltage; at 24 V AC the contacts switch 6 A, at 110 V AC 3 A, at 230 V AC 10 A, at 400 V AC 3 A, and at 690 V AC 1 A.

Integration — panel fit and wiring

The 57.5 mm height and 45 mm width make this a compact DIN-rail component for control cabinets where space is tight. Screw terminals accept 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or 2x 4 mm² solid/stranded; finely stranded with core-end processing uses the same ranges. AWG equivalents are 2x (20…16), 2x (18…14), and 2x 12 for auxiliary contact wiring. The Size S00 footprint matches the standard SIRIUS contactor family, so the relay shares mounting rails and terminal accessories with the corresponding 3RT2 contactors.

Contact reliability and switching frequency

Maximum mechanical switching frequency is 10 000 1/h for both AC and DC operation; at DC-12 and DC-13 duty the maximum operating frequency is 1 000 1/h. The apparent pick-up power of the magnet coil is 37 VA (AC), holding power 5.7 VA, with an inductive power factor of 0.8.

Frequently asked questions

How do I get current pricing and availability for 3RH6131-1AP00?

Submit an RFQ through this listing. The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time.

What is the closest functional second-source to 3RH6131-1AP00?

The 3RH6131-1BF40 is a close peer — same Size S00, same 1 NC + 3 NO contact arrangement, same 45 mm width and DIN-rail mounting. The main difference is the coil voltage: the 1AP00 is AC, the 1BF40 is DC. Both share the same auxiliary contact ratings and mechanical life. If your panel was wired for AC coil control, the 1AP00 is the direct fit; the 1BF40 would require a separate DC supply.

Will 3RH6131-1AP00 drop into a panel specified around 3RH6131-1BF40 without rewiring?

Mechanically yes — same Size S00, same 45 mm width, same DIN-rail snap-on mounting. Electrically no — the 1AP00 uses an AC coil, the 1BF40 a DC coil. You would need to verify the control supply voltage and, if the panel was wired for DC, either change the supply or use the AC version.

What compliance documentation does Siemens provide for 3RH6131-1AP00?

RoHS compliance is dated 05/01/2012. The SIRIUS series carries UL, CSA, CE, and IEC certifications per standard Siemens documentation. Specific certificate numbers are available on request with the RFQ.
