FERRAZ 重型開關系列
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
Power Plant Application

Change-over disconnect switches
HUVS 2-pole Pos 1-0-2
3600 V 8 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-current disconnectors
MBD (Multi-blade disocnnectors) range
2000V DC—5000 to 60000A
Single-pole/Double-pole/Change-over
Aluminum or copper terminals

High-current disconnectors
NORD range
1500V DC—14 kA to 140 kA
Single-pole/Double-pole/Change-over
Aluminum or copper terminals

High-current disconnectors
PBD (Plain bars disocnnectors) range
2000V DC—20 kA to 160 kA
Single-pole/Double-pole/Change-over
Aluminum terminals
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
TRACTION
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:

DC load-break switches
IF type
1000 V DC—800 to 6300 A

Disconnectors
Change-over disconnectors
FA range
3000 V AC/DC 500 to 8000 A
0 to 175 Hz
• Substation switches
DC change-over switches
DC grounding switches
AC medium-voltage disconnect switches
• Rolling stock switches
AC and DC disconnect switches
AC and DC change-over swtches with several poles and several positions, to handle main, shop, auxiliary and other sources of power
• Track and main yard switches
Catenary and third-rail switches
Load-break disconnect switches to sectionalize track
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
