Siemens Circuit breaker, 3-pole, 25kA, 415V, 80A Part number 3VA1080-3ED36-0AA0

Product Overview

The Siemens SENTRON 3VA1080-3ED36-0AA0 is a 3-pole molded-case circuit breaker from the 3VA1 series (IEC Frame 100) designed for line protection in industrial electrical systems. It features a rated operational current of 80 A, short-circuit protection permanently set at 10 × In, and a breaking capacity of up to 25 kA at 415 V (class N, Icu). This robust breaker is configured for overload and short-circuit protection for larger feeder circuits and industrial applications.
