UL 150 frame size 3-pole configuration 150A current rating 35kA breaking capacity at 480V ETU320 electronic trip unit LI protection (Long-time, Instantaneous)

Product description

The Siemens 3VA6115-5HL31-0AA0 is a 3-pole, 150A circuit breaker from the 3VA6 UL series, built on a UL frame size of 150. It provides a breaking capacity of 35kA at 480V. This breaker is equipped with the ETU320 electronic trip unit, offering LI (Long-time, Instantaneous) protection. The overload protection (Ir) is adjustable from 60A to 150A, and the instantaneous short-circuit protection (Ii) is set from 1.5 to 10 times the nominal current, without connection.

This circuit breaker is suitable for general purpose power distribution and branch circuit protection in industrial and commercial applications. The LI protection offers a balance of protection against sustained overloads and immediate short circuits.
