The right circuit breaker for any installation conditions
The range of molded case circuit breakers can be equipped with additional components so
that they can be installed as fully functional switches in any location, a feature of the product
which affords maximum flexibility to system planners.
The following components can be installed to suit the installation location:
● Front mounted rotary operator
● Door mounted rotary operator
● Side wall mounted rotary operator
● Motor operator
When the 3VA molded case circuit breaker is in the OFF position, it reliably disconnects all
current paths of the circuit in accordance with IEC 60947-2 and IEC 60204-1 (VDE 0113). In
the event of overvoltage between input and output, the reduced clearances prevent leakage
currents at the surface and ensure that the dielectric strength is not degraded. The
3VA molded case circuit breaker therefore also meets the requirements for disconnector
units according to IEC 60204-1.
The main switch or disconnector unit functionality is not diminished by installation of the
following accessory components:
● Plug-in and draw-out units
● Manual operator
● Motor operator
● Residual current device
