Side Mount Add-on Fourth Pole

The isolating switch adopts the same auxiliary
contact, and the auxiliary contact and the main
pole of the switch act at the same time.
A normally open contact with pre-disconnect
function can be provided as required.

The isolation switch can be installed with up
to four auxiliary accessories
(about 2 and 2 on the left)

The isolation switch terminal cover has a simple
appearance design, high-quality transparent
PC material,flame-retardant, high strength,
no color change after long-term use,
high-quality waterproof and easy to install.

Simultaneous or early contact operation
of the fourth pole with respect to the
switch disconnector poles.

Rotating Handle

The switch adopts compression contact
opening and closing technology, and has the
function of complete disconnection indication.
According to its mechanical principle,
this switch can work normally in any position,
without having to consider the 
problem of dropping passengers.

The interior is made of high-conductivity
nickel-phosphorus copper, which has
good conductivity and longer service life.
The shell is made of high-strength
flame-retardant PC material,
which is fire-resistant and
flame-retardant, in one step!

Rotating handle, with anti-misoperation
padlock design to prevent misoperation,
safe and reliable; Using high-quality
flame-retardant materials, insulation
and impact resistance; elegant andstylish
design, beautiful and durable.
