Product information

Description

The Hager MCN340 3P Circuit Breaker 40A 6kA Type C is a dependable modular device engineered to protect electrical circuits from overloads and short circuits. Designed by Hager, this 3-pole circuit breaker operates efficiently at an AC input frequency of 50 to 60 Hz with a nominal current rating of 40 A. Featuring a C-characteristic, it is well-suited for handling moderate inrush currents typical of commercial and residential applications.

Advantages

This circuit breaker delivers reliable performance for modern electrical installations by ensuring robust circuit protection. Its 3-pole design allows for simultaneous disconnection of multiple phases, enhancing overall safety during maintenance or fault conditions. The construction facilitates seamless integration into standard modular distribution boards, making it a practical choice for professional electricians and installers seeking dependable safety components.

Suitable for

  • Protecting 3-phase residential electrical distribution systems
  • Safeguarding commercial building wiring and sub-panels
  • Preventing damage from overloads and short circuits in motors or lighting groups
  • Modular electrical enclosures and distribution boards

When it may not be suitable

This device is not designed for industrial applications requiring breaking capacities significantly higher than 6kA. Additionally, it may not be appropriate for circuits with high startup surge currents that demand a D-characteristic breaker.

Key specifications

  • 3-pole configuration
  • Nominal current of 40 A
  • Breaking capacity of 6kA
  • Type C tripping characteristic
  • AC input frequency of 50 to 60 Hz

How to use

Installation should be performed exclusively by a qualified electrician in compliance with local electrical safety regulations and wiring codes. Mount the modular device onto a standard DIN rail inside an appropriate distribution enclosure. Ensure all terminal connections are securely tightened to the manufacturer's specified torque before restoring power to the circuit. Regularly inspect the installation for signs of wear or thermal stress.

What to consider before purchase

  • Verify that the 40 A nominal current matches your load requirements
  • Ensure the 6kA breaking capacity meets your installation standards
  • Confirm compatibility with your existing DIN rail distribution board
  • Check that the C-characteristic aligns with your connected appliances
Usage recommendations: Periodically test the circuit breaker operation and inspect terminal connections to ensure long-term reliability and safety in electrical installations.
