Product FAQs
5 answersWhich Siemens panelboards are compatible with this 3VA41 frame breaker?
It is designed for use in Siemens P1, P2, and P3 panelboards, as well as Siemens switchboards. You will need the appropriate mounting strap kit or hardware specific to your panelboard type to install this bolt-on breaker.
What wire gauges are accepted by the factory lugs?
The included lugs accept 14 to 8 AWG copper wire and 12 to 8 AWG aluminum wire. Always verify the required torque settings printed on the breaker faceplate before finalizing your terminations.
Is the 3VA4120-5ED24-0AA0 suitable for DC voltage applications?
Yes, this breaker is rated for DC applications up to 250VDC, providing an 85kA interrupting capacity. This makes it suitable for specific industrial DC control applications requiring a 2-pole configuration.
Are the thermal and magnetic trip settings adjustable on this model?
No, this specific 3VA41 frame breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous protection without field adjustability.
Can this breaker be used in a 600V system?
It is rated for 600Y/347V systems with an 18kA interrupting capacity. It is not suitable for straight 600V delta systems, as the slash voltage rating requires a solidly grounded wye system where the line-to-ground voltage does not exceed 347V.
