PROBLEM TO BE SOLVED: To provide a universal trip unit of a circuit breaker device. SOLUTION: This universal trip unit 10 for use with a circuit breaker device 1 comprises a communication unit 40 configured to communicate with a personality module 3 and to thereby receive key breaker personality parameters P2 that relate to operational characteristics, and a controller 50. The controller 50 includes a memory 60 on which a universal register R, previously stored key parameters P1 and the received key breaker personality parameters P2 are stored, and components to execute trip protection when at least one of a current and a voltage within the circuit breaker device 1 exceeds a respective predetermined threshold as defined by the previously stored key parameters P1 and the key breaker personality parameters P2.
