Our activity switchgear comprises low voltage gear, low voltage and medium voltage cabinets as well as the range of high voltage. As basic modules we employ equipment of the following lines:
LTSIST fuse isolators
LS 4 up to LS 307 contactors
MBS motor protective switches
Gerapid CC ultrarapid breakers
Low voltage transformers for measuring
ESS electronic controls
Low voltage switch cabinets
We supply standard factory assembled switch cabinets and type tested motor cabinets. The following sketch shows the standard modular cabinet of a motor protective cabinet SEV 32.
Particularly for breakers there is a preference for plug-in technique. It allows a maintenance and inspection of the breaker in service with short intervals. The plug-in breaker will be pushed into the plug holder (firm portion) across sliding rails. After plugging in the breaker the electrical connection of the main conductors is obtained through contact bridges, which are mounted on a mobile frame of isolating material elastically.
