Miniature Circuit Breakers for Direct Current circuits protection A DC current breaker protects electrical devices and circuits from facing any damage by automatically shutting off power when there is a suspected threat of an overload. In addition, the breaker is responsible for instantly interrupting the flow of electricity when a fault is detected.

Photovoltaic installations DC curent switch disconnectors 20A-1000VDC, 32A-800VDC, 50A-700VDC Acti9 C60NA-DC, Acti9 C120NA-DC and Acti9 SW60-DC are switch-disconnectors dedicated to the disconnection of direct current photovoltaic circuits
