Product FAQs
7 answersCan the 3VA6115-5HN31-0AA0 replace older Siemens ED-frame breakers?
Yes, this 3VA61 frame breaker can serve as a direct upgrade path for discontinued 150A ED-frame breakers, such as the ED63B150, when installed with the appropriate Siemens retrofit kit.
Is the Siemens 3VA6115-5HN31-0AA0 suitable for reverse feed applications?
Yes, Siemens 3VA6 electronic trip circuit breakers are UL listed for reverse feed applications. This allows the breaker to be back-fed safely in panels or switchboards.
What does the LSI designation mean on the ETU350 trip unit?
LSI stands for Long-Time, Short-Time, and Instantaneous trip functions. The ETU350 electronic trip unit allows you to adjust the long-time overload (Ir) and short-time short-circuit (Isd) pickup settings to achieve precise selective coordination in your electrical system.
What is the adjustable continuous current range for this 150A breaker?
The ETU350 LSI trip unit on the 3VA6115-5HN31-0AA0 allows the long-time continuous current (Ir) to be adjusted from 60A up to the maximum 150A rating.
What are the short-circuit adjustment ranges for the ETU350 trip unit?
The short-time pickup (Isd) can be adjusted from 1.5 to 10 times the long-time setting (Ir). The instantaneous pickup (Ii) is fixed at 10 times the nominal 150A rating, which equals 1500A.
What frame size is the 3VA6115-5HN31-0AA0?
This breaker belongs to the Siemens 3VA61 frame size, which covers electronic trip molded case circuit breakers up to a 150A maximum continuous current.
Can this breaker be used in DC systems?
No, the Siemens 3VA6115-5HN31-0AA0 is equipped with an electronic trip unit (ETU350) which is designed exclusively for AC voltage systems up to 600V. Thermal-magnetic breakers are typically required for DC applications.
