The 10 A rating at 24 V covers most PLC output and indicator circuits; at 230 V the contacts are rated for 6 A, and at 400 V for 3 A, so the same block handles mixed-voltage control panels without derating surprises. Depth of 117 mm is the dimension from DIN rail face to the front of the terminals; plan for finger-safe cover clearance. ## Contact ratings across voltages The four contacts are rated for switching at multiple voltage levels — a single block covers control voltages from 24 V up to 690 V. At 24 V the contacts carry 10 A; at 60 V, 4.7 A; at 110 V, 3 A; at 220 V, 1.2 A; at 230 V, 6 A; at 400 V, 3 A; at 440 V, 0.5 A; at 500 V, 2 A; at 600 V, 0.26 A; and at 690 V, 1 A. The arcing time is 10 to 15 ms at AC and 4 to 15 ms at DC, with a mechanical life of 10 million operations. These are the numbers that govern whether the contactor holds up in a given circuit — the 24 V and 230 V figures are the ones most buyers will check first for control transformer or PLC output duty. The substance prohibitance date of 10/01/2009 aligns with RoHS compliance — the part meets the EU RoHS exemption framework in effect from that date.","metaTitle":"Siemens 3RH2244-1AP00 SIRIUS Auxiliary Contactor, 4 N/O, 10","metaDescription":"Siemens SIRIUS 3RH2244-1AP00 auxiliary contactor. 4 instantaneous contacts, 10 A rated at 24 V.

The 3RH2244-1AP00 has four N/O contacts, while the 3RH2422-1AB00 has a different contact arrangement (typically 2 N/O + 2 N/C). The physical footprint and mounting are identical, so it drops into the same panel slot without rewiring the DIN rail — but the contact configuration change means the control circuit logic must be reviewed."},{"question":"What compliance documentation does Siemens provide for this part?","answer":"The part carries a substance prohibitance date of 10/01/2009, which aligns with RoHS compliance.
