Product information

Description

The Hager MCS340 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and industrial environments. This device is designed to interrupt current flow in the event of an overload or short circuit, effectively safeguarding connected equipment and wiring. With its Type C tripping characteristic and a 40A rated current, it offers a reliable solution for managing electrical loads that may have moderate inrush currents.

Advantages

The primary benefit of the Hager MCS340 is its integration of QuickConnect technology, which significantly reduces installation time and ensures a secure, vibration-resistant connection without the need for traditional screw terminals. The 3-pole configuration allows for the simultaneous disconnection of three phases, providing comprehensive safety for three-phase electrical systems. Its compact design, occupying only 3 modules on a standard DIN rail, maximizes space efficiency within distribution boards while maintaining high operational reliability and durability.

Suitable for

  • Protection of three-phase electrical circuits
  • Industrial machinery and motor control centers
  • Residential distribution boards for high-load appliances
  • Commercial electrical installations requiring reliable short-circuit protection

This circuit breaker may not be suitable for applications requiring a different tripping curve, such as Type B for sensitive electronic equipment or Type D for high-inductive loads with significant starting currents. Additionally, it is not intended for use in environments exceeding its specified temperature or humidity ratings, and it should not be installed in circuits where the prospective short-circuit current exceeds the device's rated breaking capacity.

Key specifications

  • Number of poles: 3
  • Tripping characteristic: Type C
  • Rated current: 40A
  • Mounting type: DIN rail
  • Width: 3 modules
  • Connection technology: QuickConnect

To install the Hager MCS340, ensure the main power supply is disconnected. Mount the device onto a standard 35mm DIN rail within the distribution board. Utilize the QuickConnect terminals to insert the stripped conductors firmly into the designated ports until they are locked in place. Verify that all connections are secure and that the wiring corresponds to the electrical diagram of the system before restoring power.

What to consider before purchase

  • Verify that the 40A rating matches the load requirements of your specific circuit
  • Ensure the Type C characteristic is appropriate for the connected equipment
  • Check available space in the distribution board for a 3-module wide device
  • Confirm compatibility with existing DIN rail mounting systems
For optimal performance and safety, ensure that all electrical installations are performed by a qualified professional in accordance with local electrical regulations. Regularly inspect the circuit breaker for signs of wear or damage and test the functionality periodically to maintain system integrity.
