Product details

It carries a 10 A continuous rated current at 24 V, with a surge voltage resistance of 6 kV, and offers 2 instantaneous contacts (NO/NC configurable).

The 45 mm width and 60 mm height fit standard S00 contactor footprints; the 73 mm depth leaves clearance for wiring and auxiliary blocks. Accepts solid or stranded conductors from 0.25 to 2.5 mm² on the terminals. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, giving flexibility in tight enclosures.

Rated for operation from -25 to +60 °C, storage and transport from -55 to +80 °C. Shock resistance is 10g at 5 ms and 5g at 10 ms. Pollution degree 3 (industrial environment). RoHS compliance date is July 1, 2006, covering substance prohibitions. Contact reliability is rated at one incorrect switching operation per 100 million operations at 17 V, 1 mA.

Frequently asked questions

Where can I buy 3RH1122-2AP00-0TK1 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — no stock figures or lead-time numbers are published here.

What is the closest functional second-source to 3RH1122-2AP00-0TK1?

The 3RH2122-2AV00 is a peer in the same SIRIUS family, but it's a different size (S0 vs S00) and carries different contact ratings. The 3RH1122-2AP00-0TK1 is size S00 with a 10 A continuous rating; the 3RH2122-2AV00 is size S0 with higher current capacity. They are not drop-in replacements without panel rework.

What is the depth of 3RH1122-2AP00-0TK1?

The depth is 73 mm.

What wire sizes does 3RH1122-2AP00-0TK1 accept?

It accepts solid conductors from 0.25 to 2.5 mm², 2x per terminal.

Will 3RH1122-2AP00-0TK1 drop into a panel specified around 3RH2122-2AV00?

No — the 3RH1122-2AP00-0TK1 is size S00 (45 mm wide), while the 3RH2122-2AV00 is size S0 (wider footprint). Panel cutouts and DIN rail spacing differ; rewiring and possibly a new mounting rail are required.

What compliance documentation does Siemens provide for 3RH1122-2AP00-0TK1?

RoHS compliance is declared with a substance prohibition date of July 1, 2006. The part carries an IP20 front protection rating. Standard Siemens documentation includes a CE declaration and IEC/EN compliance for auxiliary contactors.
