Product FAQs
6 answersCan I install the 3VA6580-6HN32-0AA0 in existing Siemens panelboards?
This breaker is designed for Siemens P4 and P5 panelboards, as well as Siemens switchboards. When retrofitting into existing P5 panels or switchboards, specific 3VA branch strap kits or OEM bus kits are required to properly mount the 3VA65 frame.
How does the LSI trip function on the ETU350 operate?
The ETU350 electronic trip unit provides adjustable Long-Time for overload protection, Short-Time for short circuit delay, and Instantaneous for immediate short circuit protection. This allows panel builders to fine-tune the breaker's response curve to coordinate with other protective devices in the electrical system.
How do I connect cables to the nut keeper terminals on this breaker?
Nut keeper terminals do not include standard mechanical wire lugs. Instead, they provide a captive nut assembly on the breaker pads. This design accepts bolt-on compression lugs or direct busbar connections on both the line and load sides.
Are mechanical wire lugs included with the 3VA6580-6HN32-0AA0?
No, this model ships exclusively with nut keeper terminals. If you need to terminate standard bare copper or aluminum wire, you must purchase compatible Siemens mechanical lug kits separately.
Is the 3VA6580-6HN32-0AA0 a direct physical replacement for legacy Siemens 800A breakers?
No. While it upgrades older 800A frames with modern electronic trip technology, the 3VA65 frame has different physical dimensions. You will need the appropriate 3VA retrofit mounting hardware to install it in existing switchboards or panels that previously housed older frame types.
Is the 3VA6580-6HN32-0AA0 suitable for heating and cooling equipment?
Yes, this breaker is HACR rated. It is certified for safe use with heating, air conditioning, and refrigeration equipment that requires a high-capacity 800A disconnect.
