Product FAQs
6 answers
Which Siemens panelboards accept the ED62B080 breaker?
This ED-frame breaker mounts via a bolt-on connection and is designed for Siemens SENTRON P2, P3, P4, and P5 commercial panelboards, as well as compatible switchboards. It will not fit in standard residential plug-on load centers.
Can this 2-pole breaker be installed in a 3-phase panelboard?
Yes, a 2-pole ED-frame breaker can be installed in a 3-phase P2, P3, P4, or P5 panelboard. It will connect to two of the three available bus bars, providing single-phase power to the connected load.
Are the lugs on the ED62B080 rated for both copper and aluminum wire?
Yes, the standard factory lugs accept both copper (Cu) and aluminum (Al) conductors. The acceptable wire range is 10 AWG to 1/0 AWG. Always apply an approved oxide inhibitor when terminating aluminum wiring.
Can I adjust the trip settings on the ED62B080?
No, this breaker uses a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip points are factory set and cannot be modified in the field.
Can the ED62B080 be used in direct current (DC) systems?
Yes, this thermal-magnetic breaker is rated for DC applications. It provides an interrupting capacity of 30kA at 250VDC, making it suitable for specific industrial control and battery system applications.
What is the difference between the ED62B080 and ED62B080L catalog numbers?
The "L" suffix in Siemens catalog numbers typically indicates that the breaker is supplied with factory-installed line and load lugs. The standard ED62B080 configuration already includes these lugs, making the two part numbers functionally identical for most installations.
