The coil draws 0.8... 1.1 A at 50 Hz and is specified for 48 V rated value at 50 Hz. This is the control-side component that energizes the contactor armature — if the coil fails, the contactor drops out regardless of the load circuit condition.
This coil mounts onto SIRIUS contactors that accept the standard screw-terminal coil connection. The 110 V AC control supply voltage (50/60 Hz) matches the common panel control voltage in European and many Asian installations. No auxiliary contact block is included — this is just the magnet coil assembly.
