Combined circuit breaker 6kA type AC HNB-B13/1N/003 195120

Combined circuit breaker – comprehensive protection for electrical installations

This circuit breaker combines the functions of an overcurrent and residual current device, providing comprehensive protection for electrical installations and user safety. The device effectively protects against the effects of short circuits, overloads and electric shock, minimizing the risk of damage and fire. It is an ideal solution for both professional installers and demanding end users.

The circuit breaker is designed for mounting on a DIN TH 35 rail and operates independently of the mounting position (vertical/horizontal). It has double screw/busbar terminals, which facilitates the connection of wires with a cross-section from 1 to 25 mm². This makes installation quick and convenient, and the device can be easily adapted to existing infrastructure.

Functionality and characteristics

The Eaton HNB-B13/1N/003 combined circuit breaker is characterized by high reliability and durability. Its construction is based on a type B tripping characteristic, which means an immediate response to current increase. AC sensitivity ensures that the device effectively detects alternating leakage currents. The rated short-circuit breaking capacity Icn is 6 kA, which guarantees effective disconnection of the circuit in the event of a failure.

• Double terminals: Allow connection of both screw and busbar wires, increasing installation flexibility.

• Contact position indicator: Red/green indicator allows for quick visual verification of the device status.

• Testing every 6 months: Recommended regular testing (button "T") ensures proper operation of the circuit breaker.

• Protection against unwanted tripping: Ensures stable device operation and minimizes the risk of false alarms.

• Overvoltage category III and energy limitation class III: Guarantee resistance to interference in the electrical network.

• Protection degree IP20: Means protection against touching with a finger and solid bodies with a diameter greater than 12.5 mm.

• Possibility of sealing: Allows securing the device against unauthorized access and changes to settings.

Application and compliance with standards

The HNB-B13/1N/003 combined circuit breaker is used in electrical installations in residential, commercial and industrial buildings. It is particularly recommended for protecting lighting circuits, socket outlets and other electrical devices requiring protection against overload and short circuit. The device meets the requirements of EN 61009-1 and EN 60898 standards, which confirms its safety and compliance with applicable regulations. The rated insulation voltage Ui is 500V and the rated impulse withstand voltage Uimp is 4kV, which ensures a high level of safety.
