The C25H42D100 is a Schneider Electric ComPacT NSX moulded-case circuit breaker in the NSX250H frame, rated 100 A at 40 °C with a MicroLogic 2.2 electronic trip unit.
Protection profile and deployment context
The MicroLogic 2.2 trip unit provides LSoI protection: long-time overload (L), short-time short-circuit with fixed delay (So), and instantaneous short-circuit (I). This breaker is intended for distribution applications in panels where the backplate mount and front-connect terminals suit fixed installation.
Integration notes
The 4-pole design places the neutral on the left. Five accessory slots accept auxiliary contacts, shunt trips, or communication modules — leave room in the panel for future additions. Mechanical durability is 20,000 cycles; electrical durability ranges from 20,000 cycles at 440 V at half rated current down to 5,000 cycles at 690 V at full rated current.
