Overview
3NP5 fuse switch disconnectors are controls for the occasional manual switching/isolating of loads and distribution boards. They are able to switch on, control and switch off the specified rated current (including a specific overload).
With the 3NP5 fuse switch disconnectors, all poles of downstream electric loads can be safely disconnected from the system under load.
