It operates on a 500 V AC 50 Hz / 550 V AC 60 Hz control circuit, drawing 155–190 W inrush at 20 °C (170–200 W at 60 Hz) and holding at 22–35 W (25–40 W at 60 Hz). The coil resistance measures 101.9 Ω at 20 °C, and the closed-circuit inductance is 9.2 H. The 500 V AC 50 Hz / 550 V AC 60 Hz control voltage is specific — this coil will not operate on 480 V or 600 V class supplies without a transformer. The operational voltage limits are 0.85 to 1.1 times Uc at 50 Hz and 60 Hz up to 55 °C, so a 500 V nominal supply can sag to 425 V and still pick up the contactor. The low-consumption coil type draws less hold-in power (22–35 W) than standard coils, which reduces heat inside the enclosure when the contactor is sealed in for long periods.","metaTitle":"Schneider TeSys WB1HA500 contactor coil, 500V AC 50/60Hz, ob","metaDescription":"Schneider Electric TeSys WB1HA500 contactor coil for CV1B/CV3B contactors. 500 V AC 50 Hz / 550 V AC 60 Hz control circuit.
