The Eaton Cutler-Hammer UVH4RP08K Undervoltage Release is a 120 VAC UVR accessory for L-frame contactors. It provides undervoltage protection by releasing the contactor coil when the supply voltage drops, ensuring the controlled circuit does not re-energize after a power interruption. Identified by the UVH4RP08K designation, this unit is intended for use with Eaton Cutler-Hammer L-frame installations in electric motor control and other control-panel applications requiring voltage-sensing protection. By integrating this UVR with the appropriate contactor, technicians can achieve safer, more reliable control of electrically driven loads in industrial environments.
