The Siemens Industry Automation Division has developed a new series of compact fuse switch disconnectors offering improved protection for staff and plants, as well as more convenient connection.

The reach-round and touch protection incorporated as standard in the new Sentron 3NP1 series prevents users from touching current conducting parts when the devices are mounted in a busbar system, even if they need to be accessed at the back.

Thanks to the IP40 degree of protection, these fuse switch disconnectors provide reliable overload and short-circuit protection for industrial or infrastructure plants.

With their compact design, they guarantee extra space in the control cabinet. Five different sizes can be supplied from 160 to 630 A. The large inspection window means the fuses installed can be instantly recognised.

All device types can be mounted quickly and easily on mounting plates, rails, or 40 or 60mm busbar systems.
