3VA6 molded case circuit breakers
The new 3VA6 molded case circuit breakers reliably perform all the tasks required for line
protection.
This range is designed for applications with more exacting requirements:
● Increased breaking capacity
● Compact dimensions
● Integrated metering function
● Connection to a fieldbus communication system
The key features of the 3VA6 range are:
● Compact dimensions
● 3 and 4-pole versions
● Four breaking capacity classes with breaking capacities of
– 35 kA to 150 kA with 480 V AC
– 18 kA to 50 kA with 600 V AC
● Fixed-mounting, plug-in technology, draw-out technology
● Electronic trip units (ETU)
● Retrofittable communication for ETU 5-series and 8-series
● Depending on the ETU: Integrated metering function for voltages, currents, powers, etc.
● AC applications
● No derating up to +50 °C
● Modular and easy-to-fit internal accessories with diverse functions
● Uniform accessories platform across all 3VA UL molded case circuit breakers
● Electronic Trip Units (ETU) with different setting values
Compact dimensions with expanded functionality
Besides the expanded functionality, the 3VA6 molded case circuit breaker is also
characterized by its compact dimensions for fixed mounting. In addition, plug-in and draw-out
sockets are available for 3VA6 molded case circuit breakers. Standard switches can be
retrofitted for these mounting methods with little effort.
Moreover, the different breaking capacity classes available and the many possibilities
afforded by the various electronic trip units also provide the flexibility needed for planning.
