Size S00 frame keeps the footprint tight at 45 mm wide, 60 mm tall, 114 mm deep — fits standard DIN-rail or screw-mount panels. Terminals accept solid or stranded conductors 0.25–2.5 mm² (2x per clamp). Front face is IP20 rated; side clearances are 0 mm, so blocks can be ganged without spacing. ## Rated operational currents AC-12: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, 1 A at 690 V. DC switching: 1 A at 110 V, 0.27 A at 220 V.","metaTitle":"Siemens 3RH1244-2AP00 SIRIUS Auxiliary Contactor, 4 NO, 10 A","metaDescription":"Siemens 3RH1244-2AP00 SIRIUS auxiliary contactor, 4 NO contacts, 10 A AC-12 rated, 45 mm wide, screw/snap-on mount.
