Switch disconnectors LAS
Generalities
The modular switch disconnectors of LAS series allow the
breaking and the disconnecting on load of equipment
on low voltage at nominal current from 16 A to 125A.
Use
The switch disconnectors of LAS series are commonly
used for the following purposes:
nmain switch
nswitch for motors
nsafety switch
ndisconnector
Additional poles
Fourth switched pole, solid neutral and earth pole.
Operating mechanism
Black (standard execution) or emergency direct handle
padlockable in 0 position.
Handle with and without door interlock handle, black or
emergency handle padlock with up to three padlocks in
0 position.
IP 65 degree of protection on door interlock handle.
General characteristics
nhigh breaking capacity (AC 22 A - AC 23 A)
ndouble break contacts
nhigh electrical and mechanical endurance
nresistant to damp heat
nIP20 degree of protection
n
modular execution, basic mounting on 35 mm DIN
rail and by screws, modular window 45mm
