Product FAQs
8 answersWhich panelboards are compatible with the 3VA4140-4ED14-0AA0 circuit breaker?
This bolt-on breaker is designed for use in Siemens P1, P2, P3, P4, and P5 panelboards, as well as compatible Siemens switchboards.
What wire sizes are accepted by the lugs on this 3VA41 frame breaker?
The included load-side lugs accept copper or aluminum wire ranging from 14 AWG to 8 AWG. Ensure proper torque specifications are followed during installation.
Can the 3VA4140-4ED14-0AA0 be used in DC applications?
Yes, this breaker is rated for 125VDC systems with a 14kA interrupting capacity, making it suitable for specific direct current control or distribution circuits.
Does this breaker feature adjustable trip settings?
No, it utilizes a thermal-magnetic trip unit with fixed long-time and fixed instantaneous (LI) trip functions, meaning the trip curve cannot be field-adjusted.
What is the interrupting rating for this 1-pole breaker on a 277V system?
When installed in a 277VAC system, it provides a 25kAIC interrupting rating. It also offers up to 65kAIC at 120VAC for high fault current applications.
How does the 3VA4140-4ED14-0AA0 mount into the panelboard?
It features a bolt-on mounting style, securing directly to the busbars of compatible Siemens Sentron panelboards for a reliable, vibration-resistant connection.
What type of protection does the integrated trip unit provide?
The thermal-magnetic trip unit provides standard overload protection through its long-time delay and short-circuit protection via its instantaneous magnetic response.
Can the 3VA4 series replace legacy Siemens breakers?
The 3VA4 series serves as a modern upgrade for various legacy Siemens bolt-on breakers. However, mounting hardware, strap kits, or filler plates may differ when retrofitting older P-series panelboards.
