Product details

It is rated for 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V, with a surge voltage resistance of 6 kV.

Mounts on DIN rail via screw or snap-on fastening. The S00 frame takes a 45 mm wide footprint, 57.5 mm tall, 72 mm deep. Accepts solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² per terminal. Shock resistance is 10g for 5 ms and 5g for 10 ms. Pollution degree 3 rated.

Contact Configuration & Ratings

The 2 instantaneous NO contacts switch at 50 Hz (0.8–1.1 A) or 60 Hz (0.85–1.1 A) with a 24 V rated value. The auxiliary switch extension is possible, meaning additional contact blocks can be added to the front. No delayed, leading, lagging, or make-before-break switching is provided — this is a straight 2 NO auxiliary contactor for signal or control circuit isolation.

Frequently asked questions

Where can I buy 3RH1122-1AB00-0TK1?

This part is sourced and quoted to order through independent distribution; submit an RFQ for availability and current pricing.

What is the depth of 3RH1122-1AB00-0TK1?

The depth is 72 mm.

What conductor sizes does 3RH1122-1AB00-0TK1 accept?

It accepts solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² per terminal.

Will 3RH1122-1AB00-0TK1 drop into a panel specified for 3RH2422-1AB00 without rewiring?

Both are S00 frame auxiliary contactors with screw/snap-on mounting and similar dimensions, but the 3RH2422-1AB00 has a different contact configuration and coil voltage — verify the contact arrangement and coil rating before substituting.

What compliance documentation does 3RH1122-1AB00-0TK1 have?

The part has a RoHS substance prohibition date of July 1, 2006. The manufacturer's standard documentation package includes the declaration of conformity and product certificate; request these with your RFQ.
