## Summary description

The Hager NDN125 is a single-pole miniature circuit breaker designed for reliable electrical circuit protection. It features a D-curve characteristic, a rated current of 25A, and a breaking capacity of 10kA. Suitable for AC systems with an input voltage range of 230-400V, this device ensures safety in residential and commercial electrical installations by preventing overloads and short circuits.

## Long description

The Hager NDN125 is a high-quality single-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and commercial environments. This device is specifically designed to detect and interrupt overcurrents, effectively preventing damage from short circuits and electrical overloads. With its D-curve characteristic, it is particularly well-suited for circuits that experience high inrush currents, ensuring stable operation without nuisance tripping.
Advantages
This circuit breaker offers exceptional reliability and safety for modern electrical installations. Its 10kA breaking capacity ensures that it can handle significant fault currents, providing a high level of security for connected equipment and wiring. The compact design allows for efficient use of space within distribution boards, while the D-curve tripping characteristic makes it an ideal choice for protecting inductive loads such as motors, transformers, and large lighting systems that require a higher tolerance for temporary current surges during startup.
Suitable for
Protecting circuits with high inrush currents
Inductive loads such as motors and transformers
Residential electrical distribution boards
Commercial electrical installations
Lighting systems with high startup demands
When it may not be suitable
This device is not intended for use in circuits where a B or C curve characteristic is required, as the D-curve is specifically calibrated for high-surge applications and may not trip quickly enough for sensitive electronic equipment. It is also not suitable for DC electrical systems.
Key specifications
Number of poles: 1
Rated current: 25A
Tripping characteristic: D-curve
Breaking capacity: 10kA
Input voltage range: 230-400V AC
How to use
The Hager NDN125 is designed for professional installation on a standard DIN rail within an electrical distribution board. It should be installed by a qualified electrician in accordance with local electrical regulations. The input and output cables are secured using the integrated terminal screws, ensuring a firm and safe connection. Once installed, the toggle switch allows for manual control of the circuit, and the device will automatically trip to the off position in the event of an electrical fault.
What to consider before purchase
Verify that the 25A rating matches your circuit requirements
Ensure the D-curve characteristic is appropriate for your specific load type
Confirm compatibility with your existing distribution board rail system
Check that the installation environment meets the voltage specifications
Usage recommendations
Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to test the functionality of the device periodically to ensure it remains in optimal working condition. Always consult a professional if you are unsure about the electrical load requirements of your system.
