The Eaton UVR120APK undervoltage release mechanism is a molded case circuit breaker accessory designed to automatically trip compatible Eaton EG-, JG-, and LG-frame breakers when control voltage drops below a safe operating level. This ensures reliable protection by disconnecting the circuit during undervoltage conditions, helping prevent equipment damage and unstable system operation. It is intended for field installation and features a left-hand mounting configuration.
