Circuit breaker EATON xPole Home HN-C40/1 1P C 40A 6kA AC (MPN 194835)

EATON xPole Home HN-C40/1 is a single-pole circuit breaker with a C characteristic and a rated current of 40 A, designed for overcurrent protection in residential and light commercial electrical installations. The device features combined thermal-magnetic tripping to protect against overloads and short circuits and is suitable for mounting on standard 35 mm DIN rails. Its rated breaking capacity of 6 kA AC ensures reliable interruption of fault currents within its designed application range.

Advantages

The single-pole design and C trip curve provide a balance between sensitivity to short-circuit currents and tolerance for inrush currents from motors or lighting loads. Thermal-magnetic operation offers dependable overload protection and fast magnetic response to high fault currents. Compact DIN-rail compatibility simplifies installation in standard consumer units and sub-distribution boards, while standardized terminals enable secure conductor connections and straightforward wiring.

Suitable for

• Residential electrical distribution boards and consumer units
• Small commercial premises with general lighting and socket circuits
• Protection of circuits with moderate motor start currents and inductive loads
• Retrofit projects where DIN-rail components are required

Key specifications

• Poles: single-pole (1P)
• Tripping characteristic: C curve (thermal-magnetic)
• Rated current: 40 A
• Breaking capacity: 6 kA AC
• Mounting: 35 mm DIN-rail
• Application: overcurrent protection for lighting, sockets and small motor loads

How to use

Install the circuit breaker in a compliant distribution board on a standard 35 mm DIN-rail, ensuring the supply and load conductors are connected to the correct terminals and tightened to the manufacturer’s recommended torque values. Use the breaker as the protective device for a single-phase circuit, observing local wiring regulations and selecting appropriate upstream and downstream protective coordination. Test the installation by switching the breaker on and off and verify correct operation under normal load conditions. All work should be carried out by a qualified electrician.

Usage recommendations

Select the C characteristic where occasional inrush currents (for example from motor starts or certain lamp types) are expected; for purely resistive or highly sensitive electronic loads consider different trip characteristics. Ensure the breaker’s rated current matches the conductor sizing and expected continuous load, and verify coordination with residual-current devices and upstream protection to maintain selectivity and safe fault interruption.
