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.","metaTitle":"Siemens 3RH6131-1AP00 SIRIUS Contactor Relay, 1NC+3NO, 6A at","metaDescription":"Siemens SIRIUS 3RH6131-1AP00 contactor relay, Size S00, 1 NC + 3 NO auxiliary contacts, 6 A at 24 V AC. 45 mm wide, snap-on DIN rail.

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."},{"question":"Will 3RH6131-1AP00 drop into a panel specified around 3RH6131-1BF40 without rewiring?","answer":"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."},{"question":"What compliance documentation does Siemens provide for 3RH6131-1AP00?","answer":"RoHS compliance is dated 05/01/2012.
