3VA1 molded case circuit breakers
The new 3VA1 molded case circuit breakers reliably perform all the tasks associated with
line protection.
Features
The key features of the 3VA1 series are:
● Compact design
● Depending on size: 1 and 2-pole versions in size 160 A, 3 and 4-pole versions in sizes
100 A, 160 A and 250 A
● Depending on size: Breaking capacity of 16 kA ... 70 kA at 415 V, 3 or 4-pole breakers
and 36 kA at 240 V,1-pole breakers
● Fixed-mounted, plug-in version
● Thermal-magnetic trip units
● AC/DC 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
Compact dimensions
Thanks to a mounting depth of 70 mm and a cover size of 45 mm, the 3VA1 molded case
circuit breakers of sizes 100 A, 160 A and 250 A are ideal for protecting cables and lines in
the plant area, especially for the INSTA electrical installation area. For these applications,
there is also a wide range of accessories available such as adapters for installation on DIN
rails, as well as residual current devices (RCD310 and RCD510) that can be side mounted.
Thermal-magnetic trip units
3VA1 molded case circuit breakers are equipped with a thermal-magnetic trip unit which
provides overload and short-circuit protection. This has been developed for implementing
economical, cost-efficient installations up to 250 A. It is suitable for use in three-phase
networks, AC networks, 400 Hz applications, and with DC currents.
