## Summary description

The Hager NDN320 is a 3-pole miniature circuit breaker designed for reliable electrical circuit protection. It features a 20A rated current and a 10kA breaking capacity, suitable for 400V AC systems. This device ensures safety by automatically disconnecting power during overloads or short circuits, making it an essential component for industrial and residential electrical distribution boards.

## Long description

The Hager NDN320 is a high-performance 3-pole miniature circuit breaker engineered to provide robust protection for electrical installations. Designed for use in 400V AC systems, this device reliably monitors current flow and automatically interrupts the circuit in the event of an overload or short circuit, preventing damage to wiring and connected equipment. Its compact design allows for efficient integration into standard electrical distribution boards, ensuring safety and operational continuity in both residential and industrial environments.
Advantages
This circuit breaker offers exceptional reliability and durability, meeting stringent safety standards for electrical distribution. The 10kA breaking capacity ensures that the device can safely handle significant fault currents, providing superior protection compared to standard breakers. Its 3-pole configuration makes it ideal for protecting three-phase circuits, while the high-quality construction from Hager guarantees long-term performance and consistent operation under various electrical loads.
Suitable for
Three-phase electrical distribution boards
Industrial machinery and equipment protection
Residential power supply systems
Commercial building electrical infrastructure
When it may not be suitable
This device is not intended for use in single-phase circuits where a 1-pole or 2-pole breaker would be sufficient. It is also not suitable for DC electrical systems, as it is specifically designed for AC applications.
Key specifications
Rated current: 20A
Number of poles: 3
Breaking capacity: 10kA
Rated voltage: 400V AC
Tripping characteristic: D-curve
How to use
The Hager NDN320 is designed for installation on a standard DIN rail within an electrical distribution board. Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is snapped onto the rail and connected to the incoming and outgoing power lines using the integrated terminal clamps. Once installed, the toggle switch allows for manual operation to disconnect or reconnect power to the circuit as needed.
What to consider before purchase
Verify that the 20A rating matches the requirements of your electrical circuit.
Ensure the D-curve tripping characteristic is appropriate for your specific load type, such as motors or transformers.
Confirm that your distribution board has sufficient space for a 3-pole modular device.
Usage recommendations
Always ensure that the power supply is completely disconnected before attempting to install or replace the circuit breaker. Regularly inspect the device for signs of wear or damage to maintain optimal safety levels.
