Combined circuit breaker 6kA type AC HNB-B6/1N/003 195118

Combined circuit breaker – protection and convenience in one device

This 6kA AC type combined circuit breaker, catalog number 195118, combines the functions of an overcurrent and residual current device, providing comprehensive protection for the electrical installation. This is an ideal solution for both professional installers and end-users looking for reliable protection. The device is designed to operate in AC networks with a voltage of 230V and a frequency of 50Hz.

Functionality and application

The HNB-B6/1N/003 circuit breaker protects circuits against the effects of overloads, short circuits and electric shock. Thanks to its B characteristic, the circuit breaker reacts quickly to current increases, but is also resistant to short-term surges, which is particularly important when connecting devices with electric motors. The use of this type of circuit breaker is crucial in places where a high level of safety is required, such as apartments, single-family homes or public buildings. Its compact design (2 modules wide) allows you to save space in the switchgear cabinet.

Advantages and product features

• Comprehensive protection: Combining overcurrent and residual current functions in one device ensures complete safety of the installation and users.
• Fast reaction: B characteristic guarantees quick disconnection of the circuit in case of overload or short circuit.
• High short-circuit breaking capacity: The rated short-circuit breaking capacity is as high as 6kA according to EN 61009-1.
• Universal application: Designed to operate in AC networks with a voltage of 230V and a frequency of 50Hz.
• Double terminals: Equipped with double screw/busbar terminals facilitating the installation of wires with a cross-section from 1 to 25 mm². This simplifies installation and allows for flexible connection of wires.
• Contact position indicator: An intuitive indicator (red/green) informs about the status of the device – whether it is on or off.
• Testing every 6 months: The requirement to test every 6 months ensures continuous efficiency of the device and increases the level of safety.
• Simultaneous disconnection of the N pole: Ensures complete disconnection of the circuit in case of failure.
• Degree of protection IP20: Protection against touching with a finger and solid bodies larger than 12.5 mm.
• Operating temperature: The device can operate in a wide range of temperatures from -25°C to +40°C.

This circuit breaker meets the requirements of IEC/EN 61009-1 and has a CE certificate, which confirms its compliance with European safety standards. Thanks to this, you can be sure that you are investing in a high-quality product that will provide reliable protection for your electrical installation for a long time.
