The Eaton UVH4LP26K undervoltage release mechanism is a molded case circuit breaker accessory designed to automatically trip compatible Eaton L-frame and M-frame breakers when control voltage falls below the required operating level. This ensures reliable system protection by disconnecting power during undervoltage conditions, helping prevent equipment damage and unstable operation. It is intended for field installation and uses pigtail lead connections with left pole mounting.
