The 12 kV impulse withstand voltage (Uimp) confirms the insulation can handle lightning or switching surges common in industrial mains. Category B selectivity means the breaker is designed for full discrimination with downstream devices, so a fault on a branch circuit trips only the nearest upstream breaker, not the main. It also meets IEC 61557-12 for measuring equipment in power systems. ## Mechanical and electrical endurance Mechanical durability is rated at 25,000 cycles with periodic preventive maintenance — typical for a main breaker in a distribution panel that sees infrequent switching. Electrical durability is 500 cycles at 1150 V AC, which governs the number of load-break operations under rated voltage before contact wear requires replacement. Maximum breaking time is 25 ms, and maximum closing response time is 70 ms — these are the fault-clearing and reclose timing windows for coordination studies.","metaTitle":"LV846550 MasterPact MTZ2 4P Circuit Breaker, 800 A, 50 kA","metaDescription":"LV846550 MasterPact MTZ2 4P fixed circuit breaker, 800 A rated current at 40 °C, 50 kA service breaking capacity at 1150 V AC.
