The Eaton UVH4LP28K undervoltage release mechanism is a molded case circuit breaker accessory designed to automatically trip compatible Eaton breakers when control voltage falls below the required operating level. This helps ensure system safety by disconnecting the circuit during undervoltage conditions, reducing the risk of equipment damage and unstable electrical operation. It is intended for field installation and uses pigtail lead connections with a left-side mounting configuration.
