Chint NB1-63 vs Schneider Acti9 iC65N: MCB Comparison (2026)

By Nick Zhu, low-voltage electrical specialist · Updated July 2026

Choosing between the Chint NB1-63 and the Schneider Acti9 iC65N miniature circuit breaker (MCB)? Both are IEC 60898 devices for final-circuit protection up to 63A — the real differences are breaking capacity options, ecosystem, availability and price. Here is a side-by-side comparison.

Chint NB1-63 vs Schneider iC65N — Comparison Table

Attribute Chint NB1-63 Schneider iC65N
Type / Standard MCB · IEC 60898-1 MCB · IEC 60898-1
Rated current (In) 1–63A 1–63A
Breaking capacity (Icn) 6kA (10kA option) 6kA
Tripping curves B, C, D B, C, D
Poles 1P–4P 1P–4P
Certifications CE, CB, CCC CE, CB, VDE, UL
Accessories / ecosystem Standard DIN modular Extensive Acti9 ecosystem
Availability Very wide, global stock Premium distribution
Relative price $ — value $$$ — premium
Best for Cost-sensitive & OEM Premium/spec-driven projects

Which Should You Choose?

Both breakers meet IEC 60898-1 with identical B/C/D curves and 1–63A ratings. The Schneider iC65N brings a premium brand, the vast Acti9 accessory ecosystem and extra approvals (VDE, UL). The Chint NB1-63 delivers equivalent core protection — with a 10kA option — at a substantially lower cost and much wider global availability. For budget-sensitive, high-volume or OEM projects, NB1-63 (or NewTrend's own DZ47/iC60N) is a strong, proven choice; where the Schneider ecosystem or spec is mandated, choose iC65N.

How NewTrend Helps

NewTrend / SNTELEC supplies genuine Chint and Delixi products plus its own NewTrend-brand range from one source, with UL/CE/RoHS/CB/SAA certification and flexible MOQs. To find the right equivalent for any Schneider, ABB or Siemens model, use our circuit breaker & contactor cross-reference chart.

Frequently Asked Questions

Is the Chint NB1-63 a direct replacement for the Schneider iC65N?

They share the same IEC 60898 standard, 1–63A ratings and B/C/D curves, so the NB1-63 is a functional equivalent for most final circuits. Always confirm breaking capacity, poles and curve match your design.

Which is cheaper, Chint NB1 or Schneider iC65N?

The Chint NB1-63 is typically far lower cost than the Schneider iC65N while meeting the same IEC standard — a key reason it is popular for value and OEM projects.

What is the NewTrend equivalent?

NewTrend supplies genuine Chint NB1-63 plus its own DZ47-63 / iC60N MCBs (UL, CE, RoHS, CB, SAA). See our cross-reference chart for equivalents to any Schneider, ABB or Siemens MCB.
