Eaton / Cutler-Hammer BR3030 30/30A Tandem Miniature Circuit Breaker

The BR3030 is a non-CTL (non-circuit total limiting) tandem breaker. It lacks a rejection clip, allowing it to be installed in older pre-1967 load centers or panels that do not require notched bus bars. For panels requiring a CTL rejection clip, the BD3030 is the correct equivalent.

Yes. Eaton manufactures the BR series to be fully backward compatible with legacy Bryant, Westinghouse, and Challenger Type BR load centers. The BR3030 directly replaces older 30/30A tandem breakers from these brands.

The BR3030 is a twin or duplex breaker that provides two independent 30-amp, single-pole circuits while only occupying a single 1-inch space in the load center. This makes it ideal for adding capacity to a full panel.

No. The BR3030 is specifically designed for Eaton, Cutler-Hammer, Bryant, and Westinghouse Type BR load centers. It is not interchangeable with Square D, Siemens, GE, or other manufacturer panels, as mixing brands violates UL listings.

No. Because both circuits in a tandem breaker connect to the same bus bar leg, they provide 120V to neutral but 0V between the two terminals. It cannot supply 240V. For a 240V appliance, you must use a standard 2-pole breaker like the BR230, which spans two bus bar legs.

No. Both circuits on a tandem breaker draw from the same phase leg. If they share a neutral wire, the neutral could become overloaded. Multi-wire branch circuits require a 2-pole breaker that spans two different phases.
