The VW3AE0118 is a 230 V undervoltage coil for the circuit-breaker inside an Altivar floor-standing enclosure with separate air flows or the compact version. It is listed for the Altivar 71 Plus-LH, Altivar 61 Plus-LH, Altivar 71 Plus, and Altivar 61 Plus ranges.
The 230 V rated supply means the coil is designed to operate on a standard 230 VAC control circuit. It drops out the circuit-breaker when the voltage falls below the undervoltage threshold, protecting the drive and motor from a brownout or phase loss.
