Westinghouse 458D070G09 undervoltage release (UVR) is a 12 VDC coil device designed for left‑hand mounting in Westinghouse equipment. It is identified as TYPE KA JA LB UVR and serves as an undervoltage release accessory. When the supply voltage falls below its 12 VDC rating, this UVR triggers the release to facilitate tripping of the connected circuit, helping protect electrical systems and maintain safe operation.
