Description
Designed to maintain older electrical infrastructure, this 80A, 600VAC-rated molded case circuit breaker offers proven thermal-magnetic protection for commercial facilities. The unit-mount configuration integrates into classic ITE and Siemens FC, FCI, and CDP panelboards. While the ED62B080 serves as its modern substitute, utilizing this original E-frame model eliminates the need for complex panel modifications. It features fixed thermal and magnetic trip settings for standard branch circuits.Specifications

Product FAQs
7 answersWhich panelboards are compatible with the EF2B080 circuit breaker?
This legacy E-Frame breaker is a direct fit for classic ITE and Siemens FC, FCI, and CDP series panelboards, allowing you to add or replace circuits without upgrading the entire enclosure.
Is the Siemens EF2B080 still in active production?
The EF frame is a legacy product and is no longer in active production by Siemens. It is typically sourced for maintaining or expanding existing older systems.
What is the modern replacement for the EF2B080 breaker?
The Siemens ED6 frame, specifically the ED62B080, serves as the modern cross-reference substitute. It offers the same 600V rating and physical footprint for upgrading older EF-frame installations.
Can the EF2B080 be utilized in direct current applications?
Yes, this breaker is certified for DC systems. It provides a 10kA interrupting capacity at 250VDC, making it suitable for specific industrial control or backup power applications.
How is the EF2B080 secured during installation?
It utilizes a bolt-on, unit-mount configuration. The breaker must be mechanically fastened to the panelboard bus or backpan, ensuring a secure connection for high-vibration or heavy-duty environments.
Is the trip unit on the EF2B080 adjustable?
No, this breaker features a non-interchangeable, fixed thermal-magnetic trip unit. Both the long-time and instantaneous trip functions are factory set and cannot be modified in the field.
Does the EF2B080 include ground fault or arc fault protection?
No, this is a standard thermal-magnetic breaker equipped with long-time and instantaneous (LI) trip functions only. It does not provide GFCI or AFCI protection.
