Product FAQs
6 answersWhich panelboards accept the ED43B030 breaker?
This ED frame breaker bolts directly into Siemens P1, P2, and P3 panelboards, as well as standard Siemens switchboards.
Will the Siemens ED43B030 replace an older I-T-E ED43B030?
Yes. Siemens acquired I-T-E, making this current Siemens Sentron breaker the exact replacement for legacy I-T-E ED43B030 units used in existing panel installations.
What wire size do the load lugs on the ED43B030 accept?
The standard factory load lugs accommodate 10 AWG through 1/0 AWG copper or aluminum conductors.
What is the modern 3VA series equivalent to the ED43B030?
For 3VA series upgrades, the direct equivalent is catalog number 3VA5130-4ED31-0AA0. Note that installing a 3VA breaker into an existing ED frame space requires a specific adapter kit.
Can I add field-installable accessories to this breaker?
Yes. The ED43B030 supports internal modifications including shunt trips, auxiliary switches, alarm switches, and undervoltage releases.
Is the ED43B030 suitable for reverse-feed applications?
Yes. This thermal magnetic breaker is rated for reverse feed, allowing it to be used safely in back-fed panel configurations.
