Control voltage flexibility
Rated at 240 V for both 50 Hz and 60 Hz AC supplies and also for DC, this coil eliminates the need to match a specific control voltage type. The AC/DC designation means the coil's internal design handles the RMS value of AC and the steady DC value equally — no derating or external rectification required. For a commissioning engineer wiring a panel that could be fed from either a utility transformer (50/60 Hz) or a backup DC bus, this coil removes a potential mismatch point.
