The Eaton Cutler-Hammer UVH1RP11K F Undervoltage Release is an undervoltage release (UVR) accessory for compatible Cutler-Hammer breakers, designed to trip the breaker when supply voltage falls below a preset level and prevent closing until normal voltage is restored. In product references it is listed as UVR 1490D70G25, identifying its place within Eaton’s UVR family. This accessory is used to protect electrical equipment such as motors and transformers by ensuring the breaker cannot remain closed during undervoltage events. Confirm compatibility with your specific Cutler-Hammer breaker model before installation.
