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.
