Product details

It switches control signals — not motor power — so its ratings are at the contact level: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V.

The S00 footprint is 90 mm wide, 57.5 mm high, 72 mm deep — that depth is the dimension you check when the panel door clearance is tight.

Contact configuration and wiring

Two instantaneous NO contacts, no leading or lagging delays, no make-before-break. The terminal block accepts solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². That covers most control wiring from signal loops to heavier interposing relays.

Substance prohibition date of 01.07.2006 aligns with RoHS compliance.

Frequently asked questions

What is the depth of 3RH1422-1AP00?

The depth is 72 mm. That's the dimension from the DIN-rail mounting base to the front face, so check panel door clearance if you're tight on space.

What wire sizes does the terminal accept?

Solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². That covers most control wiring from signal loops to interposing relays.
