Portfolio
The 3VA molded case circuit breakers set new standards in flexibility and the variety of
modular accessories available. Standardized accessories suitable for use with several sizes
of the 3VA molded case circuit breaker up to 1000 A together with quick and easy installation
help to cut costs and save time.
Sizes
The integrated 3VA portfolio consists of two different ranges of molded case circuit breakers
in twelve frame sizes. The 1600 A frame size of the 3VA2 molded case circuit breaker and
the 400 A and 630 A of the 3VA1 molded case circuit breaker are new.
The 3VA1 molded case circuit breakers are available in 1 to 4-pole versions (3VA1 160 A) or
in 3 and 4-pole versions (3VA1 100 A to 630 A). The 3VA2 molded case circuit breakers are
available in 3 and 4-pole versions.
The circuit breakers are suitable for rated operational currents ranging from 16 A to 1600 A
and rated voltages up to 690 V AC, depending on the range and frame size.
Note
A separate manual is available for the 1600 A size of the 3VA27 molded case circuit breaker
(see chapter Reference documents (Page 10)). The rest of this manual will deal with the
properties and accessory components up to 1000 A in particular.
