3VA2 molded case circuit breakers
The 3VA2 molded case circuit breakers reliably perform all the tasks associated with line and
generator protection.
This range is designed for applications with more exacting requirements:
● Increased breaking capacity
● Excellent selective protection
● Integrated metering function
● Connection to a fieldbus communication system
The key features of the 3VA2 range are:
● Compact dimensions
● 3 and 4-pole versions
● Four breaking capacity classes from 55 kA … 150 kA (at 415 V)
● Fixed-mounting, plug-in technology, draw-out technology
● Depending on size: Selective tripping at rated operational current difference 1 : 2.5 or with
ELISA 1 trip units: 1.6
● Electronic trip units
● Communication capability (ETUs 5-series and ETUs 8-series)
● Integrated metering function (ETUs 8-series)
● AC applications
● No derating up to +50 °C
● Modular and easy-to-fit internal accessories with diverse functions
● Uniform accessories platform across all 3VA molded case circuit breakers up to 1000 A
● Electronic Trip Units (ETU) with different setting values
Compact dimensions with expanded functionality
In addition to its expanded functionality, the 3VA2 molded case circuit breaker also comes
with compact dimensions for fixed mounting, as a plug-in version and a draw-out version.
A cover size of 70 mm for the door cutout (up to 630 A) and a complete selection of breaking
capacity classes from 55 kA to 150 kA at 415 V AC provide the necessary flexibility for
planning.
Despite its compact size, the circuit breaker offers the following benefits:
● Extremely high breaking capacity
● Extremely good selectivity
● Electronic trip units, versions with and without integrated metering function and optional
fieldbus communication interface
