Product FAQs
5 answersWhich panelboards are compatible with the Siemens EE2B090 circuit breaker?
The EE2B090 is designed for use in Siemens P1, P2, and P3 panelboards, as well as legacy ITE panelboards. Always verify compatibility with your specific panel's labeling before installation.
What wire sizes and materials are accepted by the lugs on the EE2B090?
The factory-installed lugs on this breaker accept 10 AWG to 1/0 AWG copper or aluminum wire.
What does the LI trip function indicate on this breaker?
The LI designation means the breaker features a thermal magnetic trip unit with fixed long-time (L) overload protection and fixed instantaneous (I) short-circuit protection.
Is there a current-generation replacement for the legacy EE2B090?
Yes, facilities looking for a modern equivalent can transition to the Siemens ED22B090, which serves as a direct replacement for this legacy E-Frame breaker.
Can the EE2B090 be installed in a 480V commercial panel?
No, this breaker is strictly rated for a maximum of 240VAC. Installing it on a 480V or 600V electrical system violates its UL listing and creates a severe safety hazard.
