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. Fastening is by screw and snap-on mounting, and the mounting position allows +/-180° rotation on a vertical surface plus +/-22.5° tilt forward and backward. 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. Contact reliability is specified as one incorrect switching operation per 100 million operations at 17 V, 1 mA — a dry-circuit rating that matters for PLC-level signal switching where oxide films might otherwise block low-energy signals.
