## Long description

The Hager MBS320 is a professional-grade 3-pole circuit breaker engineered to provide robust protection for electrical circuits in both residential and commercial environments. This device is designed to detect and interrupt overcurrents, effectively preventing damage caused by overloads and short circuits. With its compact 3-module design, it integrates seamlessly into standard distribution boards, offering a reliable solution for maintaining electrical safety and system integrity.
Advantages
This circuit breaker stands out due to its high manufacturing standards and consistent performance under load. The Type B tripping characteristic ensures rapid response to short circuits while accommodating standard inrush currents typical of household appliances and lighting circuits. Its 6kA breaking capacity provides sufficient protection for most standard electrical installations, ensuring that the circuit is safely disconnected during fault conditions. The 3-pole configuration allows for the simultaneous protection of three-phase systems, making it a versatile component for modern electrical distribution.
Suitable for
Residential electrical distribution boards
Commercial lighting and power circuits
Protection of three-phase equipment
General electrical infrastructure upgrades
This circuit breaker may not be suitable for industrial applications requiring higher breaking capacities or specific tripping curves such as Type C or D, which are better suited for high-inductive loads like large motors. It is also not intended for use in environments with extreme moisture or corrosive atmospheres without appropriate protective enclosures.
Key specifications
Number of poles: 3
Tripping characteristic: Type B
Rated current: 20A
Breaking capacity: 6kA
Module width: 3 modules
Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is designed for DIN-rail mounting within a distribution board. Ensure that the supply is disconnected before beginning the installation process. Secure the breaker firmly onto the rail and connect the incoming and outgoing cables to the appropriate terminals, ensuring all connections are tightened to the manufacturer's specified torque settings.
What to consider before purchase
Verify that the 20A rating matches the requirements of your specific circuit load.
Ensure your distribution board has sufficient space for a 3-module device.
Confirm that a Type B tripping curve is appropriate for the connected equipment.
Check compatibility with existing busbar systems.
Usage recommendations: Regularly inspect the circuit breaker for signs of wear or heat damage. It is recommended to perform a functional test of the installation periodically to ensure the protection system remains fully operational.
