These DC ratings matter because inductive loads like relay coils and solenoid valves draw an arc that DC sustains longer than AC — the contact gap and material in this contactor are designed to extinguish that arc at the listed currents. At 230 V AC, 50/60 Hz, the contacts carry 6 A; at 400 V AC, 3 A; at 690 V AC, 1 A. The 4 NO configuration means it adds isolated control-circuit switching without tying up the main contactor's auxiliary block — common in two-hand control, safety interlock chains, or PLC output expansion where you need separate confirmation of each contact closure. ## Size S00 — panel integration and mounting This contactor fits the S00 frame size (70 mm high, 45 mm wide, 121 mm deep) and mounts via screw or snap-on onto a 35 mm standard mounting rail. For a panel builder, that 45 mm width means four of these fit in a 180 mm DIN rail section — useful when stacking auxiliary contactors next to the main motor starter.","metaTitle":"Siemens 3RH2244-2AP00 SIRIUS Auxiliary Contactor, 4 NO","metaDescription":"Siemens 3RH2244-2AP00 SIRIUS auxiliary contactor, 4 NO contacts, Size S00, screw and snap-on mounting, spring terminals.
