Portfolio of 3VA27 molded case circuit breakers
The 3VA27 molded case circuit breaker is part of the Siemens 3VA portfolio that covers all
applications from 16 A to 1600 A.
Series 3VA2 circuit breakers are designed for selective tripping combined with optimum
current limiting and a high breaking capacity.
3VA2 molded case circuit breakers have been specifically designed to meet the following
requirements:
● System-wide, high selectivity with a rated current differential of 1 : 2.5 up to the miniature
circuit breaker
● Selectivity combined with effective current limiting and high breaking capacity
● Cost-effective design / configuring of selective power distribution systems
Technically these requirements of the molded case circuit breakers are met as follows:
● Dynamically opening contact system
● Coordinated electronic trip units
Depending on use of molded case circuit breakers with a rated current differential in a ratio
of at least 1 : 2.5 and selection of suitable breaking capacity classes, you can achieve
selective tripping of the area of the installation directly affected by the fault up to the
maximum ultimate short-circuit breaking capacity.
