Official documentation


Ideal applications

  • Residential electrical panels: Protection of lighting circuits, sockets, and small appliances in residential buildings.
  • Compact panels with limited space: The 1 DIN module format allows more protection devices to be installed in the same space as a traditional 2-module circuit breaker.
  • Commercial and residential final distribution: Protection of final circuits in offices, shops, and commercial premises.
  • Automated installations: Compatible with trip and low-voltage release coils, ideal for panels with remote control or remote signaling.
Frequently Asked Questions (FAQ)

Q: Which current should I choose to protect a 16 A socket circuit?
A: For a standard socket circuit (16 A), the C16 model is typically used. For circuits with loads having high inrush currents (motors, pumps), consider C20 or C25.

Q: Can this circuit breaker be combined with an RCD?
A: No, the NBH8-40 cannot be combined with RCD blocks. For residual current protection, use a separate RCD upstream.

Q: What does C Curve mean?
A: The C Curve indicates that the instantaneous magnetic trip occurs between 5 and 10 times the rated current. It is the standard curve for mixed loads (lighting, sockets, small motors). The B Curve (3–5x) is for purely resistive loads, and the D Curve (10–20x) is for motors with high inrush currents.

Q: Can I add an auxiliary contact for remote signaling?
A: Yes, the NBH8-40 can be fitted with XF9 series auxiliary contacts and XF9J series alarm contacts for remote signaling of the circuit breaker's status.
