Description

The Hager MTN132 is a robust and efficient 32A MCB (Miniature Circuit Breaker) designed to provide essential circuit protection in residential, commercial, and light industrial settings. It helps protect electrical installations from both overloads and short-circuit faults, ensuring long-term system reliability and safety.

This single pole device features a B curve tripping characteristic, which ensures the breaker trips between 3 to 5 times its rated current. This makes it particularly suitable for general-purpose circuits with low inrush currents such as lighting, socket outlets, or small domestic appliances. Its fast-acting trip function ensures rapid disconnection in the event of a fault, helping prevent damage to wiring and connected devices.

The breaker supports a 6kA breaking capacity, making it appropriate for circuits supplied by the UK’s standard low-voltage distribution network. The 1-module compact width allows for easy and space-efficient installation into Hager consumer units and DIN rail distribution boards.

Built in accordance with IEC/EN 60898 standards, the MTN132 complies with all current UK regulations, including the 18th Edition Wiring Regulations. It incorporates both thermal (overload) and magnetic (short-circuit) trip mechanisms to ensure comprehensive protection.

Key features:

  • Rated at 32A for mid-range circuit loads

  • Single pole (1P) configuration

  • B curve for standard applications

  • 6kA short-circuit breaking capacity

  • Compact 1-module design

  • DIN rail mountable

  • Compatible with Hager consumer units and boards

  • Fast terminal connection design

  • Fully compliant with IEC/EN 60898

Whether you’re replacing an old unit or working on a new installation, the Hager MTN132 32A MCB delivers performance, safety, and ease of use. It’s a trusted solution for installers and electricians looking for reliable 32A MCB protection.

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.
