Low and medium voltage switchgears
When high reliability and operational safety are necessary.
• This level of reliability can also be provided under difficult climatic and technical conditions.
• It is often a good idea to combine various devices such as isolator / earthing devices or isolator / changeover switches with an earthing device.
Standard size
Earthing switch EES 1 - 2 - 3 … 12 poles
make proof 3.6 - 7.2 - 12 - 24 - 36 kV
Earthing switch GE 1 - 2 - 3 … 12 poles
not make proof 3.6 - 7.2 - 12 - 24 - 36 kV
Isolator NT 1 - 2 - 3 … 12 poles
1 kV up to 3.6 kV - 400 A - 12 kA

DC Short circuit switch
DC High current isolator
The vacuum contacts are integrated ina switching frame (steel or stainless steel).
This results in short circuit devices with sizes ranges from 6-400 kA with switching voltages ranging from 5 V DC - 30 V DC.
In atmospheres where there is exposure to harsh chemicals, the vacuum contacts are protected against external aggressive influences and ensure a long maintenance-free service lifespan.
Installation options…
Fixed installation
at cell bottom
or into busbar system
• Type VAC 6-400 kA
Mobile
(Jumper switches)
on wheels or crane
• Type VAC-MO 50-250 kA
Mobile

Fixed installation or mobile
Watteredge vacuum contact is a patented encapsulated main contact suitable for a short, circuit, switches and DC isolator in electrolysis e. g. Chlorine · copper · nickel · magnesium · aluminium · cobalt · chrome
Switchgears for traction
In railway systems circuit breakers are required to isolate and earth currents. These circuit breakers must correspond with the technical standards stated in EN 50123-3 as well as VDE 0115.
The DC circuit breakers produced by FLOHE are capable of providing the specified on/off switching in both directions. This fulfils the requirements of excess voltage category 4 in accordance with EN 50124-1.

Flohe DC High current isolator / DC High current
load breaker
The FRGL (6 - 36 kA) has been included in the range for the task of bi-polar membrane chlorine electrolysis. It features a pre-contact for switching under load (up to 750 V DC).
EFRG isolator and FRGL load breaker combinations have been used by industries in many bipolar membrane chlorine electrolysis plants. A control unit with reverse locking is available upon request.
The FRG and FRGL isolators can be supplied for copper designs or aluminium designs. They can be securely supported just by the busbar package and do not require wall support.
Fastening brackets can be supplied on request.
