Product FAQs
5 answersWhat type of trip unit is installed in the 3VA5335-7EC31-0AA0?
This breaker is equipped with a Siemens TM230 thermal-magnetic trip unit. It provides fixed long-time thermal protection (Ir) and an adjustable instantaneous magnetic trip (Ii).
Can I adjust the continuous amperage on this circuit breaker?
No, the thermal overload protection (Ir) is fixed at the factory rating of 350A. You can only adjust the instantaneous magnetic trip (Ii) setting to coordinate with your short-circuit protection requirements.
What is the magnetic trip range for this breaker?
The adjustable instantaneous magnetic trip (Ii) on the TM230 trip unit can be set from 5 to 10 times the continuous current rating. For this 350A model, that provides a short-circuit pickup range between 1750A and 3500A.
Is the 3VA5335-7EC31-0AA0 suitable for reverse feed applications?
Yes. Siemens 3VA5 thermal-magnetic circuit breakers feature non-interchangeable trip units, which makes them UL listed and compliant for reverse feed applications.
What is the maximum frame capacity of the 3VA5335-7EC31-0AA0?
While this specific breaker is calibrated for a continuous current of 350A, it is built on the Siemens 3VA53 frame, which has a maximum physical frame rating of 400A.
