Combined circuit breaker 6kA type AC HNB-C20/1N/003 195128

Combined switch-disconnector – protection and convenience in one device

This 6kA AC type combined switch-disconnector, catalog number 195128, combines the functions of an overcurrent and residual current device, providing comprehensive protection for electrical installations. The device is designed to protect circuits with a voltage of 230V and a rated current of 20A, and its residual current sensitivity is 0.03A. This is an ideal solution for both professional installers and end-users looking for reliable and compact protection.

Functionality and application

This switch-disconnector effectively protects against the effects of short circuits, overloads and electric shock. Thanks to its C characteristic, the switch-disconnector reacts quickly to sudden current increases, but at the same time tolerates short-term load surges, which is particularly important when connecting devices with electric motors or other elements generating inrush current. Use in homes, apartments or small commercial facilities guarantees safety of use and minimizes the risk of failure. Thanks to the simultaneous disconnection of the N pole, it provides full protection against dangerous situations.

Construction and characteristic features

The Eaton xPole Home HNB-C20/1N/003 switch-disconnector is distinguished by its solid construction and thoughtful design. It has two poles (1 protected + N) and occupies only two modules on the DIN rail, which saves space in the distribution board. It is equipped with double screw/busbar terminals allowing easy mounting of cables with a cross-section from 1 to 25 mm². The contact position indicator (red/green) facilitates quick verification of the device status. Additionally, the device requires testing only every 6 months – this saves time compared to traditional solutions. It meets safety standards (CE, RoHS) and has energy limitation class 3 and protection degree IP20. Its impulse withstand voltage is 0.25kA and the rated short-circuit breaking capacity is 6kA according to EN 61009-1.
