Combined switch-disconnector 6kA type AC HNB-C13/1N/003 195126

Combined switch-disconnector – comprehensive protection for electrical installations

This 6kA type AC combined switch-disconnector is a reliable solution providing effective protection of electrical circuits against overload, short circuit and electric shock. The device combines the functions of an overcurrent and residual current circuit breaker, offering double protection in a single compact housing. It is an ideal solution for both professional installers and demanding end users.

Functionality and application

The switch-disconnector is designed to protect electrical installations in residential and commercial buildings. Thanks to its C characteristic, it provides a delayed response to short-term current surges, which is particularly important when connecting devices with electric motors or other elements generating inrush current. The rated residual current of 0.03A guarantees protection against electric shock in the event of insulation failure. The device is used in circuits with a voltage of 230V and a rated current of 13A.

Advantages and benefits

• Double protection: combining overcurrent and residual current functions in one device increases the safety of the installation and users.
• Versatility: suitable for protecting various types of circuits, including those with devices with high inrush current.
• Convenient installation: a width of 2 modules allows for easy mounting on a TH 35 DIN rail, saving space in the distribution board.
• Flexible connections: dual screw/busbar terminals facilitate the connection of wires with a cross-section from 1 to 25 mm².
• Status indicator: optical contact position indicator (red/green) facilitates quick verification of the device status.
• Testing: recommended testing every 6 months ensures continuous device efficiency.
• Compliance with standards: meets the requirements of EN 61009-1 and EN 60898 standards, guaranteeing safety and reliability.
• Durability: high resistance to shock current (0.25kA) and rated short-circuit breaking capacity (6kA) ensure reliable operation in emergency conditions.

Construction and parameters

The switch-disconnector is made of high-quality materials, ensuring its durability and reliability. The IP20 degree of protection protects against finger contact and against the influence of solid objects larger than 12.5 mm. The device operates at a frequency of 50 Hz and is adapted to operate at an ambient temperature from -25°C to 40°C. The rated insulation voltage Ui is 500V and the rated impulse withstand voltage Uimp is 4kV. The energy limitation class is 3 and the overvoltage category is III, the pollution degree is II. Thanks to this, the switch-disconnector can be used in various environmental conditions without fear of losing functionality.
