The Siemens SIRIUS 3RT1934-5AP62 is a replacement magnet coil for Size S2 contactors in the SIRIUS family.
Fit note — Size S2 form factor
This coil is dimensioned for SIRIUS Size S2 contactors — the physical envelope matches that frame.
What the voltage ratings mean in practice
The control supply voltage is AC only — don't feed it DC. At 50 Hz the rated coil voltage is 220 V; at 60 Hz it's 240 V. The pick-up and hold VA draw for a Size S2 coil will be higher than the S00/S0 frames, so verify the control transformer is sized to handle the inrush. The operating range of 0.8 to 1.1 times rated voltage means the coil pulls in reliably down to about 176 V at 50 Hz and drops out below that — useful to know if your control supply is shared with motor starters that cause a voltage dip on pickup.
