Schneider ComPact NSX100 MCCB Circuit Breaker

Core Performance & Industrial Application

The Schneider Electric ComPact NSX100 is a 100A-frame molded case circuit breaker (MCCB) from the ComPact NSX family for low-voltage line protection.

It provides thermal overload and magnetic short-circuit protection with either TMD thermal-magnetic or MicroLogic electronic trip units.

It offers multiple breaking-capacity grades (F, N, S, H) and 2P / 3P / 4P pole options to match different short-circuit levels and distribution layouts.

It supports fixed mounting on backplate or DIN panel, front-top and front-bottom wiring, and works under AC and DC networks.

It is widely used as spare replacement in factory distribution boards, motor control centers and building power panels.

Note: NSX100 is a frame family; exact breaking capacity, pole count and trip rating depend on the full order suffix.
