Product information

Description

The Hager MBS340 is a high-quality 3-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits in both residential and commercial environments. With a 40A rated current and a Type B tripping characteristic, this device is designed to detect and interrupt overcurrents and short circuits effectively, ensuring the safety of connected equipment and wiring. Its compact design occupies 3 modules of space, making it an ideal choice for modern distribution boards where space efficiency is a priority.

Advantages

This circuit breaker features advanced QuickConnect technology, which significantly simplifies the installation process by allowing for rapid and secure wire connections without the need for traditional screw terminals. The robust construction ensures long-term durability and consistent performance under standard operating conditions. By utilizing a 3-pole configuration, it provides comprehensive protection for three-phase electrical systems, offering a reliable solution for maintaining electrical integrity in various infrastructure projects.

Suitable for

  • Residential electrical distribution boards
  • Commercial building power systems
  • Three-phase lighting and power circuits
  • Protection of standard electrical appliances and wiring

This device may not be suitable for applications requiring a different tripping characteristic, such as Type C or D, which are better suited for circuits with high inrush currents like large motors or transformers. It is also not intended for use in environments exceeding its rated breaking capacity or in specialized industrial settings that require higher fault current protection.

Key specifications

  • Rated current: 40A
  • Number of poles: 3
  • Tripping characteristic: Type B
  • Mounting technology: QuickConnect
  • Module width: 3 modules

To install the Hager MBS340, ensure the power supply is completely disconnected from the distribution board. The device is designed for DIN rail mounting; simply snap the unit onto the rail until it clicks into place. Use the QuickConnect terminals to insert the conductors according to the wiring diagram of your electrical system, ensuring that each connection is firm and secure. Once installed, verify that the breaker is in the correct position before restoring power to the circuit.

What to consider before purchase

  • Verify that the 40A rating matches the requirements of your circuit load
  • Ensure the 3-pole configuration is compatible with your three-phase electrical installation
  • Confirm that the Type B tripping characteristic is appropriate for your specific connected loads
  • Check the available space in your distribution board to accommodate the 3-module width
Usage recommendations: Always ensure that the installation is performed by a qualified electrician in accordance with local electrical regulations. Periodically inspect the circuit breaker for any signs of physical damage or overheating to maintain optimal safety and performance.
