The Eaton Cutler-Hammer UVH4RP21K is a 24 VDC undervoltage release (UVR) designed for L-frame contactors. It corresponds to the UVH4RP21K part designation and is associated with reference 1483D15G42. As an undervoltage release, it disengages the coil when the supply voltage falls below the rated level, preventing unintended energization of the connected equipment.
