Product FAQs
5 answersCan the 3VA5110-4EC31-0AA0 replace older ED-frame circuit breakers?
Yes. This 3VA51 frame breaker can replace legacy 100A ED-frame breakers, such as the ED63B100. When installing it into existing Siemens P1, P2, or P3 panelboards originally fitted with ED-frame breakers, you will need the appropriate 3VA retrofit mounting kit.
What is the magnetic trip adjustment range for this 100A TM230 trip unit?
The TM230 thermal-magnetic trip unit features a fixed 100A thermal overload and an adjustable instantaneous magnetic trip. The magnetic pickup can be set anywhere from 500A to 1000A, which is 5 to 10 times the continuous current rating, allowing for precise coordination with motor inrush currents.
Are wire lugs included with the 3VA5110-4EC31-0AA0 circuit breaker?
No. While it is designed for lug terminations, the 0AA0 catalog suffix indicates this breaker ships from the factory without lugs installed. You must order the correct Siemens 3VA51 lug kits separately to match your specific wire size and conductor material.
What are the physical dimensions of the 3VA51 frame?
The 3VA51 frame is a compact 125A maximum frame size. This 3-pole breaker measures approximately 5.5 inches in height, 3 inches in width, and 3.7 inches in depth, making it suitable for high-density panelboard and switchboard installations.
Does this breaker meet UL 489 standards for commercial panelboards?
Yes, the 3VA5110-4EC31-0AA0 is fully UL 489 listed for use as a branch or feeder breaker in commercial and industrial power distribution systems.
