Description

The Hager NCN116A is a compact and high-quality 16A MCB (Miniature Circuit Breaker) built for protecting single-phase circuits from overload and short-circuit conditions. Designed for use in commercial and light industrial applications, it delivers reliable and standards-compliant protection in a space-saving format.

This breaker features a C curve tripping characteristic, which causes the device to trip between 5 and 10 times its rated current. This makes it particularly suited for circuits with moderate inrush currents such as small motors, fans, transformers, and fluorescent lighting. The C curve ensures the circuit is not tripped unnecessarily during equipment startup, while still offering fast disconnection in case of faults.

The NCN116A offers dual breaking capacity ratings:

  • 10kA in accordance with IEC/EN 60898

  • 15kA in accordance with IEC/EN 60947-2

This dual compliance makes the NCN116A suitable for a range of environments, including domestic distribution boards, commercial offices, retail units, and light industrial installations. It is ideal for situations where higher fault currents may be present.

The 1-module width allows for easy DIN rail installation, with clearly marked terminals and solid screw connections that ensure fast and secure wiring. The device is fully compliant with UK wiring regulations (18th Edition) and manufactured to Hager’s high engineering standards.

Key features:

  • 16A rated current

  • Single pole (1P) design

  • C curve – suited to inductive/resistive loads

  • 10kA/15kA short-circuit breaking capacity

  • DIN rail mountable (1 module)

  • Thermal and magnetic trip mechanisms

  • Certified to IEC/EN 60898 & 60947-2

  • Ideal for commercial lighting, fans, and motor circuits

The Hager NCN116A 16A MCB is a dependable choice for electricians seeking compact, efficient protection for general-purpose single-phase circuits. Wherever you need robust 16A MCB protection with excellent fault tolerance, this breaker is a solid performer.

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.
