Product details

The Siemens 3RH1244-1AF00 is a SIRIUS auxiliary contactor in the compact size S00 frame — 45 mm wide, 57.5 mm tall, 111 mm deep. It carries four normally-open (4 NO) instantaneous contacts with no delayed, lagging, leading, or make-before-break switching. That means it closes all four poles simultaneously on coil pickup, which is what you want for straightforward signal duplication or interlock extension in a control circuit.

The 110 V rated value is split by frequency — 0.8... 1.1 A at 50 Hz and 0.85... 1.1 A at 60 Hz.

Fastening method is screw and snap-on mounting.

Frequently asked questions

Will 3RH1244-1AF00 drop into a panel specified around 3RH2362-2AF00?

Both are size S00 SIRIUS auxiliary contactors with the same 45 mm width and screw/snap-on mounting, so the mechanical footprint and rail clip are identical. The difference is contact configuration: 3RH1244-1AF00 has 4 NO contacts only, while 3RH2362-2AF00 carries a different contact arrangement. If your panel wiring expects NC or changeover contacts, the 4 NO-only layout of this part will not match without rewiring.
