Product FAQs
6 answersWhich Siemens panels accept the ED61B020 breaker?
This breaker is compatible with Siemens P1, P2, and P3 panelboards, along with Siemens switchboards and motor control centers. Because it is a bolt-on device, it requires the appropriate mounting strap kits for your specific panel type.
What wire sizes and materials are approved for the ED61B020 lugs?
The standard load lugs accommodate 14 to 10 AWG copper conductors or 12 to 10 AWG aluminum conductors.
Is the Siemens ED61B020 a direct replacement for older ITE breakers?
Yes, this breaker directly replaces the legacy ITE Sentron ED61B020. Siemens acquired ITE and continues to manufacture this exact frame and catalog number with full backward compatibility.
What is the difference between Siemens ED4 and ED6 frame breakers?
The primary difference is the maximum voltage rating. ED6 frames like the ED61B020 are rated for up to 600VAC, whereas ED4 frames are limited to a maximum of 480VAC.
Can the ED61B020 be reverse fed?
Yes, all Siemens ED frame circuit breakers can be reverse connected. They do not have specific line or load directional restrictions, allowing for flexible installation in control panels.
Are the trip settings on the ED61B020 adjustable?
No, this breaker features a non-interchangeable thermal magnetic trip unit with fixed long-time and instantaneous (LI) trip functions. The trip curve cannot be adjusted in the field.
