Product FAQs
6 answersWhat panelboards are compatible with the 3VA4125-6ED24-0AA0 breaker?
This bolt-on molded case circuit breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as Siemens switchboards. Installation into these panels requires the appropriate 3VA41 twin mounting strap kit, which must be sourced separately.
Can this breaker replace older Siemens legacy breakers?
Yes, the 3VA4125-6ED24-0AA0 serves as a modern replacement for legacy Siemens HEAB Series and HED42B025 circuit breakers. You will need the correct 3VA41 mounting hardware kit to retrofit this breaker into existing panelboards.
What does the LI trip function mean for this 25A breaker?
The LI designation indicates that the thermal magnetic trip unit provides Long-Time (overload) and Instantaneous (short-circuit) protection. Both the thermal and magnetic trip settings are fixed and cannot be adjusted in the field.
Is this Siemens 3VA41 breaker suitable for DC voltage applications?
Yes, this breaker is rated for use in direct current systems, providing a 100kA interrupting capacity at 250V DC. Note that while the breaker is DC rated, Siemens P1 panelboards are generally not approved for DC voltage systems, so P2 or P3 panels should be used for DC applications.
What wire sizes are accepted by the load side lugs on this breaker?
The factory-installed lugs accept 14 to 8 AWG copper wire or 12 to 8 AWG aluminum wire. Always torque the lug screws to the manufacturer specifications printed on the breaker faceplate.
Does this breaker snap onto a standard DIN rail?
No, this is a bolt-on molded case circuit breaker designed to mount directly to the busbars of a panelboard or switchboard using a strap kit. It does not snap onto a standard 35mm DIN rail without a specialized Siemens DIN rail adapter accessory.
