Hager NCN332 3-Pole Miniature Circuit Breaker 32A C-Curve 10kA

The Hager NCN332 is a robust 3-pole miniature circuit breaker engineered to provide dependable 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 wiring and connected equipment from potential damage. With its precise engineering and high-quality construction, it serves as a critical component in modern electrical distribution boards.

Advantages

This circuit breaker offers exceptional reliability due to its high breaking capacity of 10kA, which allows it to safely interrupt significant fault currents. The C-curve tripping characteristic makes it highly versatile, as it is specifically designed to handle moderate inrush currents, such as those generated by motors or lighting circuits, without nuisance tripping. Its 3-pole configuration ensures simultaneous disconnection of all three phases, providing comprehensive safety for three-phase electrical systems.

Suitable for

• Three-phase electrical distribution boards
• Protection of motor circuits and lighting systems
• Residential electrical installations
• Commercial and industrial power distribution

This device may not be suitable for applications requiring a different tripping characteristic, such as B-curve for sensitive electronic equipment or D-curve for high-inrush loads like large transformers. It is intended for use in 400V AC systems and should not be used in DC circuits unless specifically rated for such applications.

Key specifications

• Rated current: 32A
• Number of poles: 3
• Tripping characteristic: C-curve
• Breaking capacity: 10kA
• Operating voltage: 400V AC

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is designed for mounting onto a standard DIN rail within a distribution enclosure. Ensure that the supply cables are correctly sized for a 32A load and that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the 32A rating matches your circuit requirements
• Ensure the C-curve characteristic is appropriate for your specific load type
• Check that the 10kA breaking capacity meets the short-circuit current levels of your installation
• Confirm compatibility with your existing DIN rail distribution board

For optimal performance and safety, regularly inspect the circuit breaker for signs of wear or discoloration and ensure the distribution board remains free of dust and moisture.
