Product FAQs
5 answersCan the 3VA5290-6EC31-0AA0 replace older Siemens legacy breakers?
Yes, this 3VA5 series breaker serves as a modern, drop-in replacement for legacy HFD63B090 circuit breakers in commercial and industrial power distribution systems.
How does the TM230 trip unit function on this 90A breaker?
The TM230 thermal-magnetic trip unit provides fixed thermal protection for continuous overloads and adjustable magnetic protection for short circuits. This allows electricians to fine-tune the instantaneous trip threshold for specific load characteristics.
What is the magnetic trip adjustment range for the 3VA5290-6EC31-0AA0?
The adjustable instantaneous short-circuit pickup ranges from 5 to 10 times the continuous current rating. For this 90A breaker, the magnetic trip threshold can be set anywhere between 450A and 900A.
Does the 3VA5290-6EC31-0AA0 ship with lugs installed?
No. While this breaker is designed for lug connections, the -0AA0 catalog suffix indicates it ships from the factory without lugs. Line and load lugs must be sourced separately to match your specific wire gauge requirements.
What is the maximum amperage capacity of the 3VA52 frame?
While this specific breaker is factory-set for 90A, the Siemens 3VA52 frame footprint supports configurations up to 250A. This allows for standardized mounting hardware and spacing across multiple breaker sizes in your panel.
