Product FAQs
6 answersWhich panelboards are compatible with the E43B015 circuit breaker?
This bolt-on breaker is designed for installation in Siemens Sentron panelboards, SB switchboards, and legacy ITE F-Series panelboards.
What wire sizes do the load lugs on this breaker accept?
The factory-installed load lugs accept 14-10 AWG copper wire or 12-10 AWG aluminum wire.
Can I use the Siemens E43B015 to replace an older ITE E43B015?
Yes. Siemens acquired ITE, and the Siemens E43B015 is a direct replacement for the legacy ITE E43B015 breaker.
Is this breaker suitable for direct current (DC) applications?
Yes, the E43B015 is rated for use in DC networks up to 250VDC, providing a 30kA interrupting capacity for direct current applications.
What type of trip protection does the E43B015 provide?
It features a fixed thermal-magnetic trip unit that provides both long-time thermal protection for overloads and instantaneous magnetic protection for short circuits.
Does this breaker include both line and load side lugs?
No. As a bolt-on breaker, it mounts directly to the panel bus on the line side. It includes lug terminals on the load side only.
