What is the modern replacement for the EE3B050 if I am upgrading my panel?
While the EE3B050 is still available for maintaining existing systems, facilities looking to modernize or replace E-frame breakers often use the ED23B050 as a functional equivalent in Siemens panelboards.
Can the EE3B050 be used in DC electrical systems?
Yes, in addition to its 240VAC rating, this breaker is rated for DC applications up to 250VDC with a 10kA interrupting capacity.
What wire sizes are accepted by the lugs on this breaker?
The standard factory lugs on the EE3B050 accept wire gauges from 10 AWG up to 1/0 AWG. The terminals are rated for both copper (Cu) and aluminum (Al) conductors.
Will this breaker fit in a standard Siemens residential load center?
No, the EE3B050 is a bolt-on molded case circuit breaker intended for commercial panelboards. It will not fit in residential plug-on load centers that require QP or QPH style breakers.
Does this breaker feature adjustable trip settings?
No, the EE3B050 features fixed thermal and fixed magnetic trip functions. It does not have adjustable trip dials.
