What this SIRIUS auxiliary contactor does in a panel
The 3RH2244-4AP60 is a Siemens SIRIUS auxiliary contactor in Size S00 — the smallest frame in the SIRIUS family, meant for control-circuit switching, not main motor current. It carries 4 NO instantaneous contacts rated to switch 10 A at 24 V, 6 A at 230 V, or 3 A at 400 V, covering the common control voltages found in 50/60 Hz panels. The contactor mounts via screw or snap-on onto a 35 mm DIN rail. The mounting position is flexible: ±180° rotation on a vertical surface, and ±22.5° tilt forward/backward — useful when fitting into tight gland-plate areas or angled sub-panels.
Switching ratings and what they mean for your control circuit
The 4 NO contacts are rated for AC-15 and DC-13 loads typical of solenoid and relay coils. At 24 V DC the contact carries 10 A; at 220 V DC it carries 1.2 A. The arcing time is 10–15 ms, and the mechanical life is 10 million operations — a solid figure for a control-circuit component that sees frequent cycling in a packaging or conveyor line. Clearance and creepage distances follow pollution degree 3, so the contactor is suited for industrial environments where conductive dust or condensation is present. The operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C.
Lifecycle and sourcing reality
The 3RH2244-4AP60 is sourced to order against the BOM through authorized distribution.
