Coil voltage and supply type
The 3RT5955-5AD31: This means a single coil variant covers both AC and DC control circuits at 48 V, simplifying BOM planning for panels that mix control transformer and battery-backed supplies.
SIRIUS family fit
Part of the Siemens SIRIUS product brand, the 3RT5955-5AD31 is the designated magnet coil for the S6 contactor frame — the withdrawable design allows the coil to be swapped without disturbing the main contactor wiring, a time-saver during panel commissioning or coil replacement.
