Description
Part of the legacy E-frame family, the Siemens EFC3M100 is a 3-pole, 100A molded case circuit breaker. It utilizes a thermal-magnetic trip mechanism to deliver fixed long-time and instantaneous (LI) protection for commercial facilities. Designed for unit mounting, it fits perfectly into Siemens Sentron P1, P2, and P3 panelboards and switchboards. For modern upgrades, this model crosses over to the ED63A100 replacement SKU.Specifications

Product FAQs
6 answersWhich panelboards accept the EFC3M100 circuit breaker?
This Sentron E-Frame breaker is compatible with Siemens Type P1, P2, and P3 panelboards, as well as standard Siemens switchboards and enclosures designed for unit-mount E-Frame breakers.
Will this breaker fit in legacy ITE enclosures?
Yes, Siemens maintained the Sentron E-Frame physical dimensions after acquiring ITE. The EFC3M100 can be installed in legacy ITE enclosures and switchboards that specify unit-mount E-Frame breakers.
What are the wire size requirements for the EFC3M100 terminals?
The standard lugs on this breaker accept 10 AWG to 1/0 AWG wire and are rated for both copper (Cu) and aluminum (Al) conductors.
Does the EFC3M100 plug onto the panel bus?
No, this is a unit-mount circuit breaker. It requires hardwired connections at both the line and load terminals and fastens directly to the enclosure or panel chassis.
How does the trip unit on the EFC3M100 operate?
It utilizes a thermal-magnetic trip mechanism with fixed thermal and fixed magnetic settings, providing standard long-time and instantaneous (LI) overcurrent and short-circuit protection.
What is the maximum interrupting capacity of the EFC3M100 at 480V?
While it can achieve up to 35kAIC at 415VAC, the maximum interrupting rating drops to 14kAIC when applied to a 480VAC system.
