Product FAQs
5 answersIs the Siemens EFC3M060 still in active production?
The EFC3M060 is a legacy E-Frame molded case circuit breaker. For new installations or direct replacements, Siemens officially recommends the HED63B060.
What type of enclosures or panels will accept the EFC3M060?
This unit-mount breaker is compatible with Siemens Sentron panelboards, as well as modern P1, P2, and P3 panelboard systems.
What wire gauge is required for the terminal lugs on this 60A breaker?
The factory-installed lugs accommodate wire sizes from 10 AWG up to 1/0 AWG. Ensure proper torque specifications are followed during installation.
Can I adjust the trip curve on the EFC3M060?
No. This breaker utilizes a fixed thermal-magnetic trip unit, meaning both the long-time (overload) and instantaneous (short-circuit) functions are factory set and non-adjustable.
Is this breaker suitable for high-fault current systems?
Yes, it provides robust protection with a 100kA interrupting capacity at 240VAC and 65kA at 480VAC, making it ideal for commercial and industrial facilities with high available fault currents.
