6.2.3 Applications
Fuseless load feeders can be used anywhere in industrial electrical applications where fuse,
contactor, and overload relay combinations were previously used. The increased
functionality of the motor starter protector (unlike a fuse combination, it can be used as an
EMERGENCY OFF and as a disconnector) means that a fuseless load feeder is capable of
solving numerous applications easily.
6.2.4 Application environment
3RA2 load feeders are climate-proof. They are designed for use in enclosed spaces in which
no severe operating conditions prevail (e.g. dust, caustic vapors, hazardous gases).
If they are to be installed in dusty or damp rooms, suitable enclosures must be provided.
