GS1 FUSIBLE DISCONNECT SWITCHES FROM 30 TO 800 A
Definition and Function
Range
Conformity to Standards
The GS1••• is a multipolar
manually operated fusible
disconnect switch. It is based on
the most up-to-date operated
disconnect switch technology. The
switch line is tested and approved
for use in the most stringent
applications such as “Service
Entrance Rating”.
• Seven ratings from 30 to 800 A,
using CC, J, and L fuses.
• Various operations:
• Standard, Front
• ON-OFF
• ON-OFF-Test
• Side
A complete line of IEC (DIN, BS or
French ferrule) Fusible disconnect
switches are available from 20 to
1800 A.

Product Features
Exceptional 200 KA
Short Circuit Protection
Practical Safeguard
Double Break: This modern
designed mechanism disconnects
on both sides of the fuse using two
double breaking contacts per pole.
This assures complete isolation of
the fuses in the OFF position.
The GS1 Series with the use of CC
or J type fused provides
exceptional high short circuit
protection, up to 200 kA.
Panel Space Savings
This proven switch technology has
the fuses incorporated on the top of
the switch mechanism to reduce the
foot print of the product and save
panel space as much as 50% from
the switches designed with use of
older fuse classes.
Touch Safe: Our design reduces
the danger of accidental contact
with live, energized parts. All
products are supplied standard with
fuse cover.

breaks” power circuits on load.
The switch line is tested and
approved for use in the most
stringent application such as

A Complete Range of Handles
The GS1/LK3 series offers a full line of NEMA/IP rated handles.
• Rated Type 1, 12, 4, and 4X (for indoor use)
• IP54 and IP65
All external handles are available in two colors.
• Black

Padlocking
Handles can be padlocked in the OFF position with up to three padlocks.
Meets OSHA requirements for lockout / tagout procedures. For safety
reasons, the door can not be opened when the handle is padlocked.
Door Interlock in On Position
The handles allows opening of the door in OFF position only. In the ON
position the door can not be opened. This interlocking can however be bypassed by authorized personnel.
Defeater
The defeat function allows qualified personnel to by-pass the door interlock
when the switch is in the ON position by means of a tool. This exclusive
design is also available in Type 4 and 4X ratings.
Fast and Safe Commissioning
The TEST position enables the testing of the control circuit auxiliaries
without switching the main contacts or removing the fuses. This function
provides an alternative to a separately wired push to test button.
