Combined circuit breaker 6kA type AC HNB-B10/1N/003 195119

Combined circuit breaker – comprehensive installation protection

This 6kA AC type combined circuit breaker from renowned manufacturer Eaton combines the functions of an overcurrent and residual current device. This solution provides comprehensive protection for electrical circuits, protecting against overloads and short circuits, as well as electric shock. The device is ideal for use in home (xPole Home) and public utility installations where high reliability and safety are required.

Construction and application

The HNB-B10/1N/003 circuit breaker is characterized by a compact design, taking up only 2 modules on a DIN rail. It is designed to operate in circuits with a rated voltage of 230V and a rated current of 10A. Its B characteristic ensures a quick response to short circuits, while allowing for trouble-free starting of devices with electric motors, which generate short-term current surges. Additionally, the presence of a neutral pole (N) enables effective protection against leakage currents.

The application of the circuit breaker includes protection of:

• sockets and lighting in residential premises,
• electrical circuits in bathrooms and kitchens (especially where there is an increased risk of contact with water),
• electrical devices sensitive to overvoltage and short circuits.

Key features and benefits

• Combination of two functions in one device: saves space in the distribution board and simplifies installation.
• High short-circuit breaking capacity (6kA): ensures effective protection against the effects of serious failures.
• AC sensitivity: effectively detects alternating current leakage currents, providing protection against electric shock.
• Double screw/busbar terminals: facilitate mounting and connection of wires with a cross-section of up to 25mm². This is particularly important for installers who value convenience and speed.
• Contact position indicator (red/green): allows for a quick visual assessment of the device's status – whether it is on or off.
• Required testing every 6 months: reminds you of the need for regular control of the device's condition, which increases safety.
• Voltage-independent tripping: ensures reliable operation even with voltage fluctuations.
• Compliance with standards: the device meets the requirements of EN 61009-1 and EN 61009 standards, which guarantees its safety and quality.

The Eaton HNB-B10/1N/003 combined circuit breaker is an investment in the safety and reliability of the electrical installation – both for professionals and end users. Its solid construction and advanced features provide long-term protection against the effects of electrical failures. The rated current is 10A at a rated voltage of 230V, and the short-circuit breaking capacity is 6kA. AC sensitivity and the ability to connect wires with a cross-section of up to 25mm² ensure versatile application of this device.
