Product FAQs

7 answers
Can the 3VA5335-6EC31-0AA0 replace older Siemens JD frame breakers?

Yes, the 3VA53 frame serves as a substitute for legacy Siemens JD frame breakers, including the HJD63B350. When retrofitting into existing P1, P2, or P3 panelboards, a specific 3VA connection strap kit is required.

Are terminal lugs included with this circuit breaker?

No, the -0AA0 suffix in the catalog number indicates that this breaker is supplied without lugs. Line and load lugs must be sourced separately based on your conductor size and material.

Can the trip unit on the 3VA5335-6EC31-0AA0 be adjusted?

Yes, the TM230 thermal-magnetic trip unit features an adjustable magnetic (instantaneous) setting to coordinate short-circuit protection. However, the thermal (long-time) overload setting is fixed at 350A.

What hardware is required to mount this breaker in a Siemens P-series panelboard?

To install this 3VA53 frame breaker into Siemens P1, P2, or P3 panelboards, you must use a compatible 3VA strap kit. It will not mount using legacy JD frame strap kits.

What does the Class H breaking capacity mean for this breaker?

The Class H designation indicates a high interrupting rating, specifically providing 65kAIC at 480V and 25kAIC at 600V, making it suitable for commercial and industrial systems with higher available fault currents.

What is the maximum frame size for the 3VA5335-6EC31-0AA0?

This breaker belongs to the 3VA53 frame group, which has a 400A maximum frame size. This specific unit is factory-calibrated with a 350A fixed thermal trip.

Can the 3VA5335-6EC31-0AA0 be reverse fed?

Yes, this thermal-magnetic breaker is suitable for reverse-feed applications. Always verify your specific panelboard labeling and local NEC requirements before backfeeding.
