## Long description

The Hager MBN350E is a high-quality 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and commercial environments. This device is designed to monitor current flow and automatically disconnect the power supply in the event of an overload or short circuit, thereby safeguarding your wiring and connected appliances from potential damage or fire hazards.
Advantages
This circuit breaker stands out due to its reliable performance and precision engineering. The B-curve tripping characteristic ensures a fast response to overcurrent conditions, making it ideal for standard electrical loads. Its 3-pole configuration allows for the simultaneous protection of three-phase systems, ensuring balanced safety across all phases. The compact design facilitates easy installation in standard distribution boards, while the durable construction guarantees long-term operational stability and safety compliance.
Suitable for
Protection of three-phase electrical circuits in residential buildings
Safety management in commercial office electrical installations
Overload and short-circuit protection for lighting and general power circuits
Integration into standard distribution boards and consumer units
This device may not be suitable for circuits with high inrush currents, such as those powering large motors or transformers, where a C or D-curve breaker would be more appropriate to prevent nuisance tripping. It is also not intended for use in DC electrical systems.
Key specifications
Number of poles: 3
Rated current: 50A
Tripping characteristic: B-curve
Breaking capacity: 6kA
Rated operational voltage: 230/400V AC
The installation of this circuit breaker should be performed by a qualified electrician in accordance with local electrical regulations. The device is mounted onto a standard DIN rail within an enclosure. Ensure that the supply voltage matches the specifications of the breaker before connection. Once mounted, verify that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
Verify that the 50A rating matches the load requirements of your circuit
Ensure the B-curve characteristic is appropriate for your specific application
Check that the 6kA breaking capacity meets the short-circuit current rating of your electrical installation
Confirm compatibility with your existing distribution board layout
Usage recommendations
