£38.37 EX. VAT

Description

The Hager NCN310A is a compact and high-performance 10A 3-pole MCB (Miniature Circuit Breaker) engineered for protecting three-phase electrical circuits from short circuits and overloads. With its robust design and reliable performance, it is ideal for use in commercial buildings, workshops, and light industrial installations.

Featuring a C curve tripping characteristic, this breaker is designed to tolerate moderate inrush currents—typically caused by inductive loads like small motors, transformers, or fluorescent lighting. It trips between 5 to 10 times its rated current, providing fast fault response without unnecessary interruptions to normal operation.

The NCN310A offers dual breaking capacity ratings:

  • 10kA in compliance with IEC/EN 60898

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

This flexibility ensures the device is suitable for various types of installations with different fault current levels, especially in environments where higher prospective fault currents are expected.

Its 3-module width makes it suitable for DIN rail mounting inside commercial distribution boards and control panels. The MCB is user-friendly, with clear terminal markings and secure screw connections that allow for efficient and safe installation.

Key features:

  • 10A rated current

  • 3-pole (3P) design for three-phase circuits

  • C curve – ideal for circuits with moderate inrush current

  • 10/15kA short-circuit capacity

  • 3-module compact size

  • DIN rail mountable

  • Complies with IEC/EN 60898 and 60947-2

  • Reliable protection with thermal and magnetic trip mechanisms

Whether you’re protecting lighting banks, small motors, or general distribution in a commercial installation, the Hager NCN310A 10A 3-pole MCB delivers outstanding safety and performance. For any project requiring dependable 10A 3-pole MCB protection, this model is a smart, regulation-compliant choice.

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.
