Combined circuit breaker 6kA type AC HNB-B16/1N/003 195121

Combined circuit breaker – comprehensive installation protection

The Eaton HNB-B16/1N/003 combined circuit breaker is a reliable device combining the functions of an overcurrent and residual current circuit breaker. It provides comprehensive protection of electrical circuits against the effects of overloads, short circuits and electric shock. It is an ideal solution for both installers and end-users looking for safety and ease of use.

Functionality and application

The device is designed to protect circuits with a voltage of 230V and a rated current of 16A. Characteristic B ensures fast tripping in the event of short circuits, and AC sensitivity guarantees effective protection against alternating leakage currents. The circuit breaker is used in home installations (xPole Home), providing safety in residential premises, offices and other public buildings. Thanks to its compact size (2 module width) it saves valuable space in the distribution board.

Key features and benefits

• Combination of two functions in one device: Eliminates the need to use separate overcurrent and residual current circuit breakers, simplifying installation and reducing costs.
• High short-circuit breaking capacity (6kA): Ensures effective protection against the effects of serious failures in the electrical installation.
• Double terminals (lift/busbar): Allow flexible cable mounting, adapting to different installation conditions.
• Contact position indicator: Allows quick visual check of the device status – red color indicates the need for intervention.
• Testing every 6 months: The requirement for regular testing ensures continuous device efficiency and reliable protection.
• Rated residual current 0.03A: Provides high sensitivity to leakage currents, minimizing the risk of electric shock.
• Wide range of wire cross-sections (1-25 mm²): Allows connection of cables of different thicknesses, adapting to the specifics of the installation.
• Energy limitation class 3: Provides adequate protection against the effects of overvoltage.
• Simultaneous disconnection of the N pole: Increases safety by disconnecting both the phase and neutral during a fault.

The HNB-B16/1N/003 circuit breaker is an investment in safety and peace of mind – reliable protection for your electrical installation and household members.
