Product details

It carries 4 instantaneous contacts (2 NO + 2 NC) and is designed for screw or snap-on mounting on a DIN rail.

The auxiliary contactor is rated 10 A at 24 V (AC/DC) and 6 A at 230 V, with a derating curve down to 1 A at 690 V. For a 24 VDC control circuit, the 10 A rating gives headroom for pilot duty up to NEMA A600 or IEC AC-15/DC-13 loads. The 6 A at 230 V covers most contactor coil and indicator lamp circuits in European panels. The S00 frame size — 45 mm wide, 57.5 mm tall, 72 mm deep — fits the standard Siemens 3RT1 contactor footprint, so it can be ganged alongside a 3RT1 power contactor without extra DIN rail space.

The 3RH1122-1AF00 is a direct drop-in for any panel designed around the SIRIUS S00 auxiliary contactor family.

The part carries RoHS compliance with a substance prohibition date of 01.07.2006, and is assigned reference code K per IEC 81346-2.

Frequently asked questions

Will the 3RH1122-1AF00 fit a panel designed for a 3RT1015-1AG61 contactor?

Both parts share the S00 frame size and the same 45 mm width, 57.5 mm height, and 72 mm depth. The 3RH1122-1AF00 is an auxiliary contactor that can be ganged alongside a 3RT1 power contactor on the same DIN rail without extra space. However, it is not a direct functional replacement — the 3RT1015-1AG61 is a power contactor with different coil voltage and main contact ratings. The 3RH1122-1AF00 serves as the auxiliary contact block for signalling and control.
