Product FAQs
5 answersWhich panelboards are compatible with the ED21B015 circuit breaker?
The ED21B015 is a bolt-on ED frame breaker designed for use in Siemens P1, P2, and P3 panelboards, as well as Sentron panelboards and switchboards. It requires a bolt-on connection and is not compatible with load centers that require plug-in breakers.
What wire sizes and materials are approved for the lugs on this breaker?
The factory-installed lugs accept 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire. Ensure proper torque specifications are followed during installation as outlined by the manufacturer.
Can the ED21B015 be used in DC applications?
Yes, this breaker is rated for DC applications up to 125VDC with an interrupting capacity of 5kA. This makes it suitable for specific control circuits and DC power systems requiring a 15A 1-pole breaker.
Is the Siemens ED21B015 a direct replacement for older I-T-E breakers?
Yes, Siemens acquired I-T-E and continues to manufacture this breaker under the same catalog number. The Siemens ED21B015 is a direct replacement for the legacy I-T-E ED21B015.
Does this breaker provide ground fault or arc fault protection?
No, the ED21B015 is a standard thermal-magnetic breaker providing long-time and instantaneous trip functions. It does not include ground fault (GFCI) or arc fault (AFCI) protection.
