Description

The Hager NCN106A is a high-quality 6A MCB (Miniature Circuit Breaker) tailored for low-current, single-phase circuits. This breaker offers sensitive and reliable protection against overloads and short circuits, making it especially useful for lighting, control panels, small appliance circuits, and specialised installations.

Featuring a C curve tripping characteristic, the NCN106A operates when current reaches 5 to 10 times the nominal value. This makes it perfect for circuits with moderate inrush currents—such as LED lighting arrays, small pumps, control gear, and stabilised appliances. The C curve ensures fast reaction to faults while avoiding unnecessary trips during normal start-up surges.

A key highlight of this device is its dual-rated breaking capacity:

  • 10 kA in accordance with IEC/EN 60898 (for domestic and commercial distribution)

  • 15 kA in accordance with IEC/EN 60947‑2 (industrial-standard resilience)

This provides flexibility—allowing installation in environments where moderate fault current levels may occur, such as commercial lighting boards or small machinery panels.

Thanks to its 1-module width, the NCN106A is space-efficient and mounts easily on standard DIN rails within consumer units or control cabinets. Installation is streamlined via clear labelling and sturdy screw terminals designed for secure cable connections.

Manufactured to meet the 18th Edition Wiring Regulations, this breaker combines quality and compliance with Hager’s trusted engineering standards. The reliable dual-trip mechanism—thermal (overload) and magnetic (short circuit)—ensures comprehensive protection.

Key features:

  • 6 A rated current

  • Single pole (1P) design

  • C curve tripping (5–10× rated current)

  • Dual breaking capacity: 10 kA / 15 kA

  • Compact 1-module width

  • Tool-friendly DIN rail mounting

  • Secure screw terminals

  • Fully compliant with IEC/EN 60898 & 60947‑2

  • Ideal for lighting, control circuits, small motors, and apparatus

The Hager NCN106A 6A MCB is an excellent choice when precision protection is required for sensitive or low-current circuits. Whether fitting out a control board or safeguarding specialised equipment, this 6A MCB delivers reliable, safe, and standards-compliant performance.

Frequently asked questions

An MCB is an electromechanical device used to protect electrical circuits from overcurrents. It automatically switches off the circuit if the current exceeds a predetermined threshold, thereby preventing damage to wiring, appliances, and other connected equipment.

MCBs are typically used in the consumer unit (fuse box) of single-phase installations. They protect individual circuits that supply power to sockets, lighting, appliances, and other electrical loads within homes, offices, and small businesses.

MCBs are essential for electrical safety in single-phase systems as they prevent overheating and potential fire hazards caused by excessive current flow. They ensure that circuits are automatically disconnected in case of faults such as short circuits or overloads.

When selecting an MCB for a single-phase system, consider:

  • Current Rating: Choose an MCB with a current rating that matches or slightly exceeds the maximum current expected in the circuit it protects.
  • Breaking Capacity: Ensure the MCB has a sufficient breaking capacity to safely interrupt the maximum fault current that could occur in the circuit.
  • Tripping Curve: Select the tripping curve (e.g., B, C, or D) based on the type of load and expected inrush currents to prevent unnecessary tripping.

MCBs used in single-phase installations should comply with relevant standards such as BS EN 60898 or BS EN 60947-2, depending on whether they are intended for domestic or industrial applications. Compliance ensures reliability and safety in operation.
