Disconnectors are ideally suited as main and EMERGENCY-STOP switches. Thanks to their fused design, they additionally provide short-circuit and overload protection. In connection with SITOR semiconductor fuses, they even master high requirements. 
In contrast to the 3NJ4 in-line fuse switch disconnectors, the devices of the 3NJ6 range are equipped with an integrated switching element with single- or double-break. They are particularly suitable for applications in which many cable outlets for power distribution have to be accommodated in minimum space. The intelligent plug-in connection system facilitates the devices’ easy and comfortable mounting.
New compact Sentron 3NP1 series comes with enhanced protection for personnel and plants and a sophisticated connection system. 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 on the rear.
