It operates on a 440 V AC at 50 Hz or 500 V AC at 60 Hz control circuit, drawing an inrush of 220...270 VA at 50 Hz and holding at 35...55 VA. The coil's average resistance is 233 ohms at 20 °C, which determines the steady-state current draw in the hold-in phase. Inrush power sits at 90...110 W (75...95 W at 20 °C), while hold-in power drops to 13...19 W (10...13 W at 20 °C). These figures matter for sizing the control transformer and verifying the contactor's pick-up voltage under load — the operational voltage limits are 0.85 to 1.1 Uc at 50/60 Hz below 55 °C. ## Deployment context This coil mounts into the CV1B or CV3B contactor frame, which is typically installed in motor control panels or general switching assemblies on a DIN rail or backplate. The low-consumption coil design reduces heat buildup in the enclosure, which helps when multiple contactors are ganged in a confined panel.","metaTitle":"Schneider Electric WB1EA455 TeSys Contactor Coil, 440-500 V","metaDescription":"Schneider Electric WB1EA455 TeSys contactor coil for CV1B/CV3B. 440-500 V AC control circuit.
