NH FUSE SWITCH DISCONNECTORS
KETO

The KETO discon­nector gener­a­tion allows devices of sizes 000 to 3 to be combined just as desired. Differ­ences in size are adjusted to a uniform cover cut-out with the avail­able compo­nents for touch protec­tion. Many of the func­tions are inte­grated across all sizes, for instance for cover support levels at 32mm, 60mm, 70mm and 90mm above the top of the busbar. This ensures the optimum system inte­gra­tion. Vari­ants for base­plate mounting, busbar and DIN rail mounting offer the right solu­tion for any application.

The new KETO-000 offers you the option of increasing your number of outlets without having to accept any major losses in perfor­mance. The KETO-000 is designed so that two of these devices fit exactly in the same instal­la­tion space as the size 00. This gives you two outlets of up to 125A instead of one of up to 160A.

NH fuse switch discon­nec­tors are used in the areas of building instal­la­tion, switchgear and control system construc­tion as well as in energy supply. The contact systems allows for safe switching under load, with the fuse links forming the mobile contact. 

Reversible

Reversible adap­ta­tion to rails 5mm and 10mm thick.

Variable

Easy conver­sion from bottom cable outlet to top cable outlet. 

Flex­ible

Exten­sive range of acces­sories to adapt to yourapplication.
