Mounting and disassembling load feeders

Please proceed as per the mounting instructions below for self-assembly of 3RA2 load
feeders.
Sizes S0 and S00 support three connection systems:
● Screw connection
● Spring-loaded connection
● Hybrid connection
The hybrid connection system combines screw-type and spring-loaded connection
technology. Motor starter protectors with screw connection and contactors with spring-loaded
connection can be installed together in the load feeder.
Sizes S2 and S3 are only available in the version with screw connection (main circuit).
The modular system has suitable link modules for each connection system.
