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.
