When industry-leading company worldwide have a special
challenge, they call Ferraz Shawmut. Why?
Because we’ve pioneered more technological advances in high-power
switches than all of our
competitors combine. DC and AC switches designed to handle
high current/low voltage and high voltage/low current applications, including :
Change-over disconnect
switch
HUVS 3-pole
3600 V - 1 kA
Test Lab Application
Disconnect
Switches
HAS 24 kV, single pole, 25 kA

• rectifier output
disconnect switches
• change-over disconnect switches
• change-over gorunding disconnect switches
• polarity-reversing disconnect switches
• distribution panel disconnect switches
• low-voltage disconnect switches
• medium-voltage disconnect switches
• grounding switches
• mobile and stationery shorting switches
• Pure silver-to-silver contacts for the best connection
• a visible disconnect that eliminates guesswork and increases safety
• Self-cleaning contacts for minimal maintenance
• Aluminum or copper, bolted or welded connections
• Various methods of operation-manual, electric or pneumatic
• Mechanical or electrical open-switch locks
• Multiple contacts, with spring-loaded arc-quenching chambers independent
from the main contacts
• Outdoor enclosures resistant to corrosive environments

High-power
chemical processes, like electroplating and the electrolysis of
chlorine,
fluorine and magnesium, require disconnect switches
that can handle 300 kA plus.
Ferraz Shawmut offers these as well as a range of other types of
switches, to cover the entire line from transformer to
cell. In fact, we were the first to create multiple products for
specific applications. Switches are available for flexible or fixed connections-copper or aluminum,
bolted or welded. They include :
• Medium-voltage
transformer disconnect switches
• Rectifier output disconnect switches
• Mobile and stationary shorting switches
• polarity-reversing
disconnect switches for electroplating.
• a
deformable disconnect switch that can move on three
axes to allow for bus bar expa,nsion, eliminating the need
for expensive flexible
connections
• a
proven air-cooled switch for aluminum smelting-the
first of its kind
• the first input loadbreak disconnect switch for
‘’choppers’’ - DC-to-DC converters
• the first loadbreak switch and rotating current transfer
unit for copper foil processes
• the first dual-shell switching system for DC arc furnaces
If
you’ve traveled by train anywhere in the world, chances are
Ferraz Shawmut’s high-power switches were part
of your trip. Built to take the vibration and constant punishment
of traction applications, our AC and DC switches are
found everywhere—from light rail and subway
trains to locomotives, from substations and rolling stock
to third rails.
Customer rely on us for:

The
switches can be operated manually, or they can be motorized
and operated locally or remotely, increasing safety and reliability.
Another
safety feature is a built-in interlock
that ensures the position of the switch
