Description

Designed for heavy-duty power distribution, the Siemens EE3B100 is a 3-pole, 100A molded case circuit breaker. It delivers reliable thermal-magnetic protection for commercial and industrial facilities requiring consistent performance. This E-Frame breaker installs into Siemens Sentron and older ITE panelboards via a standard bolt-on configuration. If a modern substitute is required, the ED23B100 serves as the exact replacement. It features a 10kAIC rating at 240VAC and includes load side lugs.

Product FAQs

8 answers
What is a modern replacement for the legacy EE3B100?

The Siemens ED23B100 is the direct modern equivalent, matching the 100A rating, 10kAIC at 240VAC capacity, and bolt-on E-frame footprint. If a higher interrupting rating is required, the ED43B100 is also a physically compatible replacement.

Which panelboards are compatible with the EE3B100?

This breaker mounts into Siemens Sentron power panels and older legacy ITE panelboards designed to accept bolt-on E-frame MCCBs. It is not compatible with standard residential plug-on load centers.

Does the EE3B100 include load-side lugs?

Yes, this circuit breaker comes with load-side lugs included for terminating branch circuit conductors. The line side features a bolt-on connection that mounts directly to the panelboard bus.

What wire sizes are supported by the load terminals?

The included mechanical lugs accept 14 AWG through 1/0 AWG copper or aluminum (Cu/Al) wire. Always verify torque specifications on the breaker faceplate during installation.

Can the EE3B100 be used in direct current (DC) circuits?

Yes. Along with its standard AC ratings, this breaker is rated for 250VDC systems with a 10kA interrupting capacity, allowing it to protect industrial DC control or power circuits.

Are the thermal or magnetic trip settings adjustable?

No. The EE3B100 is equipped with a non-interchangeable thermal-magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) pickup thresholds are fixed at the factory.

Is this circuit breaker HACR rated?

Yes, the EE3B100 is HACR rated, certifying it for safe and code-compliant use with heating, air conditioning, and refrigeration motor loads.

Does the EE3B100 include built-in ground fault or arc fault protection?

No, this model provides standard thermal-magnetic overcurrent and short-circuit protection. It does not feature equipment ground fault, GFCI, or AFCI circuitry.
