BR2100

The Eaton BR2100 is a ‑pole,  amp thermal‑magnetic circuit breaker from Eaton’s widely‑used BR breaker family, designed for dependable overcurrent protection in 120/240 VAC residential, commercial, and light industrial panelboards and load centers. As a Type BR breaker, the BR2100 plugs directly into Eaton BR and BR‑II panelboard bus systems without additional mounting hardware, simplifying both new installations and maintenance replacements. With a common‑trip design, the BR2100 simultaneously disconnects both ungrounded conductors under overload or fault conditions, supporting NEC‑compliant multi‑wire branch circuits and enhanced safety.

Electrically, the BR2100 employs Eaton’s thermal‑magnetic trip mechanism, which combines a heat‑sensitive element to guard against sustained overloads with a magnetic instantaneous element that responds quickly to high‑fault current events. It is UL 489 listed and typically rated for a {air rating} interrupting capacity, meaning it is capable of safely interrupting fault currents up to 10,000 amps in systems engineered to those standards. The  amp continuous current rating makes this breaker suitable for heavier branch circuits such as sub‑feeders, large loads, and high‑demand appliances or equipment, providing robust protection where significant load currents are present.

Mechanically, the BR2100 features a rugged molded case and a manual toggle actuator that offers clear ON/OFF status and simple reset after a trip. The breaker accommodates standard conductor sizes appropriate to its rating (commonly #3–1/0 AWG copper or aluminum, per panelboard specifications) and integrates seamlessly with Eaton’s accessory ecosystem for labeling, auxiliary contacts, and handle ties where needed. Its broad compatibility, thermal‑magnetic performance, and adherence to safety standards make the BR2100 a reliable choice for electricians and designers specifying dependable overcurrent protection for mid‑to‑high branch circuit applications in residential and light commercial electrical systems.
