It handles signal-level loads and pilot duty: the three NO contacts are rated for DC switching at 10 A at 24 V, 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, and 0.5 A at 440 V. For AC-15 duty at 230 V the contacts carry 10 A, and at 400 V they carry 3 A. The size S00 frame is the smallest in the SIRIUS contactor family, so this unit occupies minimal DIN-rail space: 73 mm deep, 90 mm wide, 57.5 mm tall. The side clearance required is 6 mm; forward and upward clearance is 10 mm each. ## Switching performance and endurance The contacts are instantaneous with an AC operating time of 4 to 15 ms. The operating voltage range at 50 Hz is 0.8 to 1.1 times rated value, and at 60 Hz it is 0.85 to 1.1 times rated value. RoHS compliance is documented with a substance prohibition date of 10/01/2009. The terminal wiring accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded conductors.","metaTitle":"Siemens 3RH2431-1AF00 SIRIUS Auxiliary Contactor, 3 NO, Size","metaDescription":"Siemens SIRIUS 3RH2431-1AF00 auxiliary contactor, size S00, 3 instantaneous NO contacts, 73 mm depth.
