## Long description

The Hager NDN350 is a high-performance 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding environments. Designed for reliability and safety, this device effectively monitors electrical flow to prevent damage from overloads and short circuits. With a rated current of 50A and a breaking capacity of 10kA, it serves as a critical component in maintaining the stability of electrical distribution systems in commercial and industrial settings.
Advantages
This circuit breaker offers exceptional durability and consistent performance under various load conditions. Its 3-pole configuration allows for the simultaneous disconnection of three phases, ensuring comprehensive protection for three-phase equipment. The high breaking capacity of 10kA provides peace of mind by safely interrupting high fault currents, thereby protecting downstream infrastructure and minimizing the risk of fire or equipment failure. The compact design facilitates efficient installation within standard distribution boards.
Suitable for
Industrial machinery and motor control centers
Commercial building electrical distribution boards
Three-phase power supply systems
Protection of high-load electrical circuits
This device may not be suitable for residential applications where a lower amperage rating is required or where the specific tripping characteristics of the D-curve are not compatible with the connected load. It is also not intended for use in DC electrical systems, as it is specifically engineered for 400V AC environments.
Key specifications
Number of poles: 3
Rated current: 50A
Breaking capacity: 10kA
Operating voltage: 400V AC
Tripping characteristic: D-curve
The Hager NDN350 should be installed by a qualified electrician in accordance with local electrical regulations. It is mounted onto a standard DIN rail within an enclosure. Ensure that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating and ensure optimal electrical contact. Once installed, the device can be manually switched on or off using the front-facing toggle.
What to consider before purchase
Verify that the 50A rating matches your circuit load requirements
Ensure the 10kA breaking capacity is sufficient for your installation's prospective short-circuit current
Confirm compatibility with your existing distribution board and DIN rail system
Check that the D-curve tripping characteristic is appropriate for your specific load type
Usage recommendations: Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to perform periodic testing of the switching mechanism to ensure it remains operational and to verify that all electrical connections remain secure over time.
