Circuit breaker 3P C 40A 6kA AC Eaton xPole Home HN-C40/3 (MPN 194895)

The Eaton xPole Home HN-C40/3 is a three-pole miniature circuit breaker with a C tripping characteristic and a rated current of 40 A. Designed for use in residential and light commercial distribution boards, this breaker provides thermal-magnetic protection to interrupt overloads and short circuits in three-phase AC circuits with a breaking capacity of 6 kA. The device fits standard DIN-rail mounting and is intended for use in low-voltage electrical installations where coordinated protection and reliable disconnection are required.

Advantages

The breaker combines thermal and magnetic tripping to protect circuits against prolonged overloads and instantaneous short-circuit currents. Its C characteristic ensures selective operation for moderate inrush currents common to motors and lighting loads. Compact three-pole construction saves space in distribution panels and simplifies three-phase protection by providing simultaneous disconnection of all poles. The 6 kA breaking capacity meets typical requirements for residential and light commercial networks.

Подходит для

• Protection of three-phase lighting and socket circuits in homes
• Distribution boards in small commercial premises and workshops
• Protection of motor circuits with moderate starting currents
• Upgrades or replacements in existing low-voltage panels

Key specifications

• Poles: 3 (three-pole)
• Tripping characteristic: C (thermal-magnetic)
• Rated current: 40 A
• Breaking capacity: 6 kA (AC)
• Type: Miniature circuit breaker for low-voltage distribution
• Mounting: DIN-rail compatible

How to use

Install the breaker on a standard DIN-rail inside the distribution board, ensuring correct orientation and secure terminal connections for all three phases and neutral if applicable. Tighten conductor terminals to the torque recommended by the distribution board manufacturer and verify that the supply is de-energized during installation. Use the breaker as the main protective device for the designated three-phase circuit; test operation after installation by switching the device on and off and, where safety protocol requires, perform an insulation and continuity check of the protected circuit before energizing.

Usage recommendations

Select this 40 A, C-characteristic three-pole breaker where circuits have moderate inrush currents and standard residential or light commercial short-circuit levels. Coordinate with upstream and downstream protective devices to ensure discrimination and avoid nuisance trips. For installations with higher prospective fault currents, confirm that the breaker’s breaking capacity is sufficient or choose a device with a higher interrupting rating.
