Eaton Cutler-Hammer MUVH1LB08 Undervoltage Release is a DC undervoltage release (UVR) for F-frame contactors. It operates on 110–127 VDC and is designed to trip the contactor when the supply voltage dips outside this range. As part of the Cutler-Hammer family, the MUVH1LB08 provides protection in motor control circuits by ensuring the system releases on undervoltage. This model is identified by the MUVH1LB08 designation and is used with compatible Eaton F-frame units.
