Note
On request, a transparent cover can be installed on the front of the circuit-breaker to increase the degree of protection to IP54. The cover has a
locking key.
As an alternative to the transparent cover, a protection can be mounted on the manual closing and opening controls, which only allows operation of
the pushbuttons by means of a special tool..
