BR330

The Eaton BR330 is a -pole, amp thermal‑magnetic circuit breaker from Eaton’s BR family, designed to provide dependable overcurrent protection in 120/240 VAC three‑phase distribution systems. As part of the Type BR line, this breaker is engineered for use in Eaton BR and BR‑II load centers and panelboards commonly found in residential, commercial, and light‑industrial applications. The 3‑pole configuration allows the BR330 to simultaneously protect all three ungrounded conductors in a three‑phase circuit, ensuring balanced protection and compliance with NEC requirements for multi‑phase systems.

Electrically, the BR330 incorporates Eaton’s thermal‑magnetic trip mechanism, which combines a heat‑sensitive overload element with a magnetic instantaneous trip for fast response to short‑circuit events. This design delivers reliable protection against both sustained overloads and high‑fault current conditions. The breaker is UL 489 listed and rated for a {aic rating} interrupting capacity. With a  amp continuous current rating, the BR330 is suitable for protecting smaller three‑phase loads such as motor control circuits, lighting panels, and sub‑feeders.

Mechanically, the BR330 features a compact molded case and a manual toggle actuator that provides clear ON/OFF status and easy reset after a trip. The breaker mounts via a plug‑on design into compatible Eaton load center buses without additional mounting hardware, streamlining installation and replacement. It accepts standard conductor sizes appropriate for its amp rating and integrates with Eaton’s accessory ecosystem for labeling, auxiliary contacts, and handle ties where needed. The BR330 is a practical choice for electricians and designers specifying circuit protection in three‑phase branch circuits requiring dependable, code‑compliant performance.
