## Summary description

The Hager NBN320 is a 3-pole miniature circuit breaker designed for reliable electrical circuit protection. It features a rated current of 20A and a breaking capacity of 10kA, suitable for 400V AC systems. This device provides effective overload and short-circuit protection for residential and commercial electrical installations, ensuring safety and operational stability in various power distribution applications.

## Long description

The Hager NBN320 is a high-quality 3-pole miniature circuit breaker engineered to provide robust electrical protection in both residential and commercial environments. Designed for 400V AC systems, this device ensures the safety of electrical installations by effectively monitoring current flow and disconnecting the circuit in the event of an overload or short circuit. Its compact design and reliable switching mechanism make it an essential component for modern power distribution boards, helping to prevent damage to wiring and connected equipment.
Advantages
This circuit breaker offers exceptional reliability and durability, meeting stringent safety standards for electrical protection. The 10kA breaking capacity ensures that the device can safely interrupt high fault currents, providing a significant safety margin for electrical systems. Its 3-pole configuration allows for the simultaneous disconnection of three phases, which is critical for protecting three-phase motors and other industrial or commercial equipment. The unit is designed for easy installation on standard DIN rails, facilitating efficient assembly in distribution panels.
Suitable for
Protection of three-phase electrical circuits in residential buildings
Commercial power distribution systems
Industrial machinery and motor control circuits
General overload and short-circuit protection for 400V AC installations
When it may not be suitable
This device is specifically designed for 400V AC systems and is not suitable for DC applications or circuits exceeding its rated voltage and current specifications. It should not be used in environments where the expected short-circuit current exceeds its 10kA breaking capacity.
Key specifications
Number of poles: 3
Rated current: 20A
Breaking capacity: 10kA
Rated operational voltage: 400V AC
Mounting type: DIN rail
How to use
The Hager NBN320 should be installed by a qualified electrician in accordance with local electrical regulations. The device is mounted onto a standard DIN rail within a distribution board. Ensure that the supply cables are securely connected to the input terminals and the load cables to the output terminals, following the torque specifications provided by the manufacturer. Once installed, the breaker can be manually switched on or off using the toggle lever on the front panel.
What to consider before purchase
Verify that the 20A rating matches the requirements of your electrical circuit
Ensure the 10kA breaking capacity is sufficient for your installation's potential fault current
Confirm that your system requires a 3-pole configuration
Check available space in your distribution board for a 3-module wide device
Usage recommendations: Regularly inspect the circuit breaker for signs of wear or heat damage. It is recommended to perform periodic testing of the switching mechanism to ensure continued operational readiness.
