Product details

It carries a MicroLogic 2.3 electronic trip unit with L, So, and I protection curves — overload (long time), short-time short-circuit with fixed delay, and instantaneous short-circuit. Breaking capacity is 100 kA Icu at 500 V, 525 V, and 660/690 V AC 50/60 Hz per IEC 60947-2. That is the HB2 rating — full 100 kA up to 690 V.

Connection pitch is 45 mm. Front connections both upside and downside. IP40 enclosure protection, IK07 impact resistance. That means it is rated for industrial environments inside a panel — not outdoor or washdown, but fine for a typical MCC or distribution board.

Certified to EN/IEC 60947-2. Suitability for isolation is confirmed per that standard. IP40, IK07.

Frequently asked questions

What is the closest alternative to C40W32D250 in the ComPacT NSX family?

The closest sibling is the same NSX400HB2 frame with a different trip unit rating or MicroLogic variant. No pin-compatible alternative exists outside the ComPacT NSX range; the mounting footprint and connection pitch are specific to this series.

What is C40W32D250's breaking capacity at 690 V?

100 kA Icu at 660/690 V AC 50/60 Hz per IEC 60947-2 — the HB2 rating holds full capacity at the highest voltage.

What compliance documentation does Schneider provide for C40W32D250?

Declaration of conformity to EN/IEC 60947-2, test reports for type tests per that standard. Standard Schneider documentation package available on request.
