At 690 V AC the breaking capacity drops to 50 kA Icu, still enough for most 690 V distribution applications. ## Drawout form factor and panel integration Drawout mounting means the breaker slides into a cradle on a rail or base plate — you can rack it out for maintenance or replacement without disturbing the bus connections. The rear connection terminals accept vertical or horizontal bus bar orientation, with a 115 mm connection pitch without spreader. That pitch matches standard switchgear bus spacing; if you need to adapt to a different pitch, a spreader kit is available. ## Durability and fault response Electrical durability is 5,000 cycles at 440/690 V AC without maintenance — that is the number to watch for frequent switching applications; if your process cycles the breaker daily, the electrical endurance may govern the replacement interval. Maximum breaking time is 25 ms, fast enough to limit let-through energy and coordinate with downstream breakers. The digital display shows fault type — internal fault, overload, or short-circuit — which speeds troubleshooting on a distribution board.","metaTitle":"Schneider Electric EVS12H3NW5A EasyPact EVS Circuit Breaker,","metaDescription":"Schneider Electric EVS12H3NW5A EasyPact EVS drawout circuit breaker, 1250 A rated current, 65 kA Icu at 440 V AC, IEC 60947-2.
