Coil voltage and auxiliary contact ratings
The 3RT1064-2XF46-0LA2 is a SIRIUS contactor (Size S10) with a 110 VDC coil — the DC coil eliminates the hum and power consumption of an AC coil, making it suitable for battery-backed or DC-supplied control circuits where continuous hold-in power is a concern. These ratings define the maximum DC current the auxiliary contacts can break — important for pilot-duty loads like PLC inputs or relay coils in a DC control panel.
Mechanical life and switching frequency per duty
For DC loads, the limit is 350 cycles/hour in DC-1 and 250 in DC-3/DC-5. These figures govern whether the contactor can keep pace with the process cycle time without overheating the coil or arc chamber.
Mounting, wiring, and environmental limits
Fastened by screw fixing through an 11 mm hole — the mounting surface must be vertical, with the contactor rotatable ±90° and tiltable ±22.5° front-to-back.
