Built for heavy-duty commercial distribution, this 100A SENTRON ED frame breaker delivers fixed thermal and magnetic trip responses. It handles demanding electrical loads with a 65kAIC interrupt capacity at 240V and 18kAIC at 480V. The bolt-on configuration mounts into Siemens P1, P2, P3, P4, and P5 panelboards as well as compatible switchboards. Equipped with load-side lugs only, it connects securely to the panel bus for reliable power routing in industrial facilities.
Which Siemens panelboards accept the ED43B100 circuit breaker?
This bolt-on ED-frame breaker mounts directly into Siemens Sentron P1, P2, P3, P4, and P5 panelboards, as well as compatible Siemens switchboards.
Are terminal lugs included with the ED43B100?
Yes, load-side lugs (Siemens LN1E100) are installed and accept 10 to 1/0 AWG copper or aluminum wire. Because the ED43B100 is a bolt-on panelboard breaker, line-side lugs are not included. If installing in a standalone enclosure requiring cable-in, line-side lugs must be added in the field.
Is the ED43B100 rated for reverse-feed and HACR applications?
Yes, this Sentron series circuit breaker is both HACR rated for HVAC equipment and certified for reverse-feed installations.
Does this replace the older I-T-E or Gould ED43B100?
Yes, the Siemens ED43B100 is a direct, interchangeable replacement for legacy I-T-E and Gould circuit breakers sharing the exact same ED43B100 catalog number.
What is the difference between the Siemens ED43B100 and ED63B100?
Both are 100A, 3-pole ED-frame circuit breakers, but they have different interrupting ratings. The ED43B100 is rated at 18kAIC at 480VAC, while the ED63B100 offers a higher 25kAIC at 480VAC.
