Integration into a Size S2 contactor
The 3RT5934-5AN21: This coil mounts directly onto a Siemens SIRIUS Size S2 contactor frame. The 220 V AC rating matches the standard control voltage in many European and Asian panels. The 0.8 to 1.1 A inrush at 50 Hz is the figure to use when calculating the control transformer VA budget — the holding current is lower, but the pick-up surge determines the fuse and transformer sizing.
