Plug-in technology
Plug-in technology is the less expensive and more space-saving of the two solutions. The
3VA molded case circuit breaker is inserted in the appropriate plug-in socket and fitted with
plug-in contacts which make a keyed, friction-locked connection with the corresponding
mating contacts (tulip-type contacts) in the plug-in socket. In this case, the device is plugged
in and withdrawn manually.
