200 A MCCB in the ComPacT NSX family
It is a 4-pole device (4P) with a breaking capacity code of N — 50 kA Icu at 415 V AC, 50/60 Hz, per IEC 60947-2. The trip unit provides L (thermal overload) and I (magnetic short-circuit) protection in one compact package.
For higher ambient temperatures, derating applies — the trip curve shifts, so the breaker may trip at a lower sustained current. That is a standard specification for main or feeder breakers in medium-to-large distribution boards. No earth-leakage protection is built in — that is a separate accessory.
The connection pitch is 35 mm. Both upside and downside connections are front-facing, so busbar or cable terminations are accessible from the front of the panel. The toggle control is manual; no motor operator is included. IP40 front face, IK07 impact resistance.
