It mounts via screw or snap-on onto a 35 mm DIN rail, fitting into a 57.5 mm height, 90 mm width, and 73 mm depth footprint — the S00 frame keeps panel density tight. Rated for pollution degree 3, it handles industrial atmospheres where conductive deposits may occur. Rated operational current varies by voltage: 10 A at 24 V AC and 230 V AC, 4.7 A at 60 V, 3 A at 110 V and 400 V, 1.2 A at 220 V, 0.5 A at 440 V, 2 A at 500 V, 0.26 A at 600 V, and 1 A at 690 V. The 2 NO contacts switch resistive loads up to 10 A at 230 V AC; for DC loads, the arcing time runs 10 to 15 ms, so inductive loads need the usual suppression. Mechanical life is 5,000,000 cycles typical, with a maximum switching frequency of 10,000 operations per hour on AC. Conductor cross-sections accepted: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded. The auxiliary switch extension is supported — add a front-mount block if the 2 NO contacts aren't enough. Relative humidity minimum 10%. RoHS compliance date is October 1, 2009. The part carries the SIRIUS brand and is designed for industrial control panels per IEC/EN standards.","metaTitle":"Siemens 3RH2422-1BJ80 SIRIUS Auxiliary Contactor, S00, 2 NO,","metaDescription":"Siemens 3RH2422-1BJ80 SIRIUS auxiliary contactor, size S00, 2 NO instantaneous contacts, 24 VDC coil, screw and snap-on mounting on 35 mm DIN rail.
