Eaton HN-C25/2 Miniature Circuit Breaker, 2-Pole, 25A, C-Curve, 6kA

The Eaton HN-C25/2 is a high-quality 2-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in various environments. This device is designed to monitor current flow and automatically disconnect the circuit in the event of an overload or short circuit, thereby safeguarding wiring and connected equipment from potential damage. With its compact design and reliable performance, it serves as a critical component in modern electrical distribution systems.

Advantages

This miniature circuit breaker offers exceptional reliability and durability, ensuring consistent protection for your electrical infrastructure. Its C-curve tripping characteristic makes it highly versatile for a wide range of applications, as it effectively handles moderate inrush currents without nuisance tripping. The 6kA breaking capacity provides a sufficient safety margin for standard residential and commercial installations, while the 2-pole configuration allows for the simultaneous disconnection of both phase and neutral conductors, enhancing overall safety during maintenance or fault conditions.

Suitable for

• Residential electrical distribution boards
• Commercial building power circuits
• Protection of lighting and general-purpose socket outlets
• Small motor circuits with moderate starting currents

When it may not be suitable

This circuit breaker is not intended for industrial applications requiring high breaking capacities exceeding 6kA. It is also not suitable for protecting sensitive electronic equipment that requires specialized surge protection or for circuits where the load current consistently exceeds the 25A rating.

Key specifications

• Rated current: 25A
• Number of poles: 2
• Tripping characteristic: C-curve
• Breaking capacity: 6kA
• Mounting type: DIN rail

How to use

The Eaton HN-C25/2 is designed for installation onto a standard DIN rail within an electrical distribution board. Installation should be performed by a qualified electrician in accordance with local electrical regulations. Ensure that the supply power is disconnected before mounting the device. Once securely snapped onto the rail, connect the incoming supply wires to the top terminals and the outgoing load wires to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque settings.

What to consider before purchase

• Verify that the 25A rating matches the requirements of your circuit load.
• Ensure the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
• Check that the DIN rail space is available in your distribution board.
• Confirm that the C-curve characteristic is appropriate for the types of loads being protected.

Usage recommendations

Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to test the mechanical operation of the toggle switch periodically to ensure it remains functional. If the breaker trips, investigate the cause of the overload or short circuit before resetting the device.
