Auxiliary contactor for SIRIUS control circuits
The 3RH2244-1AK60: Intended for switching control signals and auxiliary loads in motor control panels, the 3RH2244 handles DC circuits up to 10 000 operations per hour and AC switching with an arcing time of 10 to 15 ms.
Contact ratings and switching performance
Mechanical life of 10 million operations typical; switching frequency limited to 10 000 1/h on DC loads due to arc duration.
Mounting and clearances
Fastens via screw clamp or snaps onto 35 mm DIN rail; mounting position allows ±180° rotation on vertical surfaces and ±22.5° tilt forward/backward. Requires 45 mm width and 117 mm depth; keep clearances of 10 mm upward/downward, 10 mm forward, and 6 mm laterally for heat dissipation and wiring access. Accepts conductors up to 4 mm² (solid/stranded) per terminal; pollution degree 3 rated, suitable for industrial environments.
