Integrated system
The 3VA molded case circuit breakers set new standards, not only in terms of their technical
features and functional scope, but also in terms of their design.
The 3VA range provides an integrated system with regard to operation, functionality and
installation. This principle is embodied in the basic units and in all internal and external
accessories.
The internal and external accessories of the 3VA molded case circuit breakers offer the
following benefits:
● Standardized methods of operation
● Standardized scope of functions
● Standardized installation procedures
● Uniform accessories from 16 A … 1000 A (e.g. auxiliary switches, auxiliary releases, etc.)
