The front face is IP20 rated, suitable for enclosed control cabinets where finger-safe touch protection is needed during maintenance access. Clearance at the side is 0 mm, so units can be ganged without spacing. Wire termination accepts solid or ferruled stranded conductors from 0.25 to 2.5 mm² — covers standard control wiring for 24 VDC or 230 VAC pilot circuits. Depth behind the panel is 73 mm, which fits most standard enclosure depths without crowding the backplane. Rated operational current varies by voltage and duty: 10 A at 24 V (AC-12), 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. For DC switching at 110 V it carries 1 A, dropping to 0.27 A at 220 V. These are the contact ratings for auxiliary loads — signal lamps, contactor coils, PLC inputs — not motor power. The contacts are rated for 50 Hz and 60 Hz operation with a voltage range of 0.8 to 1.1 times rated value at both frequencies. Mechanical endurance is typical 30 million operating cycles — this is a high-life auxiliary block meant for frequent switching in cyclic machines or conveyor lines. Shock resistance is 10g at 5 ms and 5g at 10 ms, adequate for industrial environments with moderate vibration from adjacent contactors or drives.","metaTitle":"Siemens 3RH1122-2AP00-0TK0 SIRIUS Auxiliary Contactor, 2 NO,","metaDescription":"Siemens SIRIUS 3RH1122-2AP00-0TK0 auxiliary contactor, 2 instantaneous NO contacts, 10 A rated at 24 V.

The 3RH1122 is designed to mount alongside or on top of an S00 power contactor to add auxiliary contacts. They share the same S00 footprint and snap-on rail, but they are not drop-in replacements for each other — one adds signal contacts, the other switches motor loads."},{"question":"How do I get current pricing and availability for 3RH1122-2AP00-0TK0?","answer":"Pricing and availability are confirmed at quote time.
