Product details

Footprint and mounting

The 3RH1122-1AP00-0RC0: The S00 frame measures 45 mm wide, 57.5 mm high, and 72 mm deep — a compact footprint that fits standard DIN-rail enclosures. The front protection class is IP20, so it's suitable for enclosed panel use where accidental finger contact is prevented by the enclosure door.

Wiring and contact ratings

Solid wire terminations accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² — covering common control wiring sizes without needing ferrules. The 24 V rated value of 10 A is the headline switching capacity; at 110 V the rating drops to 1 A, at 230 V to 6 A, and at 400 V to 3 A.

Frequently asked questions

Where can I buy 3RH1122-1AP00-0RC0 and how do I get a price?

What is the closest functional second-source for 3RH1122-1AP00-0RC0?

The 3RH2122-2AV00 is a functional peer in the same SIRIUS family, but it carries different contact configurations and coil ratings. Verify the specific NO/NC count and coil voltage before substituting — the 3RH1122-1AP00-0RC0 has 2 NO + 2 NC instantaneous contacts at 24 V rated value 10 A, which may not match the peer's arrangement.

What is 3RH1122-1AP00-0RC0's listed depth?

The depth is 72 mm, with a width of 45 mm and height of 57.5 mm — the S00 frame size.

What wire sizes does 3RH1122-1AP00-0RC0 accept?

Solid wire terminations accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².

What compliance documentation does this part carry?

The substance prohibition date of 07/01/2006 indicates RoHS compliance. The part carries an IP20 front protection rating and surge voltage resistance rated at 6 kV. Pollution degree is 3, suitable for industrial environments with conductive pollution.
