That universal AC/DC input simplifies panel design — one coil variant covers both control schemes, no need to stock separate AC and DC coils. ## Coil voltage and control supply — 240 V universal This means the same part works on a 240 VAC control transformer or a 240 VDC battery-backed control bus — no derating or separate coil change needed when switching between AC and DC control architectures. Product designation is 'magnet coil' — this is the electromagnetic actuator that pulls the contactor armature closed. On the SIRIUS S6 platform, the coil is a replaceable module; the withdrawal design lets you swap it without removing the contactor from the DIN rail or disconnecting the main power cables.","metaTitle":"Siemens 3RT5955-5AP31 SIRIUS Magnet Coil, 240 V AC/DC","metaDescription":"Siemens 3RT5955-5AP31 SIRIUS magnet coil, 240 V AC/DC rated for 50/60 Hz.
