The Schneider Electric ENW24136 is a 1600 A air circuit breaker from the EasyPact NW range, built for distribution duty in industrial switchboards. It is a 3-pole drawout unit — meaning the breaker body slides out of its cradle for safe inspection or swap without disturbing the bus connections. Rated operational voltage is 690 V AC, with a breaking capacity of 66 kA Icu at 440 V AC and 50 kA Icu at 690 V AC, both per IEC 60947-2. That puts it in the H (high) breaking capacity class for this frame size. The IP40 enclosure keeps tools and fingers out but is not washdown-rated.
For a 1600 A bus or a large transformer secondary, this is the right frame size. Short-time withstand (Icw) is 65 kA for 1 second at 440 V and 36 kA for 3 seconds at 440/690 V. That delay lets downstream breakers clear a fault first — essential for selective coordination in a distribution panel. Utilisation category B confirms the breaker is designed for this selective operation with intentional short delay. Electrical durability is 6,000 cycles at 440 V without maintenance. For a main breaker that operates infrequently (a few times a year for switching), this is more than adequate. For a machine-tool disconnect cycled daily, it is not the right choice — look at a contactor-based solution instead.
Push-button control on the front panel for open/close operations. Contact position indicator gives visual confirmation of the main contact state — no need to open the door to verify.
