Product FAQs
6 answersWhat legacy Siemens circuit breakers does the 3VA5110-6EC31-0AA0 replace?
The 3VA51 frame is the modern replacement for legacy Siemens ED-frame breakers, such as the HED43B100 and HHED63B100. A retrofit mounting kit is required when upgrading older panelboards.
Does the 3VA5110-6EC31-0AA0 come with line and load lugs installed?
No. The -0AA0 suffix in the catalog number indicates this breaker ships without lugs. Line and load lug kits must be purchased separately based on your specific wire size and material requirements.
What does the 6 in the 3VA5110-6EC31-0AA0 catalog number indicate?
The 6 designates this as a Class H (High Breaking Capacity) circuit breaker, which provides a 65kA interrupting rating at 480VAC.
Is the trip unit on this 100A breaker adjustable?
Yes, it features a TM230 thermal-magnetic trip unit. While the thermal overload setting is fixed at 100A, the magnetic short-circuit trip setting is adjustable to help coordinate with other protection devices in your system.
Can this 3-pole breaker be used in 500VDC applications?
Yes, this breaker is rated for up to 500VDC with a 100kA interrupting capacity. However, achieving the maximum DC voltage rating requires wiring the poles in series according to Siemens DC application guidelines.
Which Siemens panelboards are compatible with this 3VA5 breaker?
This breaker is designed for use in Siemens P1 and P2 panelboards, as well as Siemens switchboards. Proper mounting hardware or strap kits are required for installation.
