## Long description

The Hager MCN304E 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 monitor current flow and automatically disconnect power in the event of an overload or short circuit, thereby safeguarding connected equipment and wiring from potential damage. With its reliable construction and precise tripping mechanism, it serves as a critical component in modern electrical distribution boards.
Advantages
This circuit breaker offers exceptional reliability due to its high-quality manufacturing standards. The C-type tripping characteristic provides a balanced response to current surges, making it versatile for various types of loads. Its 3-pole configuration allows for the simultaneous protection of three phases, ensuring comprehensive safety in three-phase electrical systems. The compact design facilitates easy installation in standard distribution enclosures, while the 6kA breaking capacity ensures it can handle significant fault currents safely.
Suitable for
Residential electrical distribution boards
Commercial building power systems
Industrial machinery and control panels
Lighting and heating circuit protection
This device may not be suitable for applications requiring a different tripping curve, such as B-curve for sensitive electronics or D-curve for high-inrush current motors. It is also not intended for use in DC electrical systems, as it is specifically rated for AC voltage applications.
Key specifications
Number of poles: 3
Rated current: 4A
Breaking capacity: 6kA
Tripping characteristic: C-curve
AC input voltage: 230-400V
The Hager MCN304E is installed by mounting it onto a standard DIN rail within an electrical distribution board. Ensure that the power supply is completely disconnected before attempting installation. The input and output cables should be securely fastened to the terminals, ensuring that the torque specifications are followed to prevent loose connections. Once installed, the device can be switched on manually using the toggle lever.
What to consider before purchase
Verify that the 4A current rating matches the requirements of your specific circuit
Ensure the 3-pole configuration is compatible with your electrical supply
Check that the C-curve characteristic is appropriate for your connected loads
Confirm that the 6kA breaking capacity meets local safety regulations
Usage recommendations
Always consult with a qualified electrician for the installation and maintenance of circuit protection devices to ensure compliance with local electrical codes and safety standards.
