The Eaton BD3040 is a Type BD duplex (tandem) thermal‑magnetic circuit breaker designed for use in Eaton BR load centers and compatible panelboards. It is engineered to deliver two separate protective circuits within a single 1‑inch breaker slot, commonly rated at 30 A for one half and A for the other, making it ideal for maximizing available spaces in residential and light commercial electrical panels. Duplex breakers like the BD3040 allow panels to support additional branch circuits without increasing panel footprint, helping electricians and designers meet modern load demands in space‑constrained installations.
Electrically, the BD3040 operates at 120/240 VAC service with a typical interrupting capacity of {aic rating}, ensuring safe interruption of fault currents up to 10 000 amps in properly designed circuits. Its thermal‑magnetic trip mechanism combines a heat‑sensitive element for sustained overload protection with a magnetic element that responds rapidly to short‑circuit conditions, providing dependable performance for general lighting, receptacle, and small appliance circuits. The breaker includes a rejection tab feature to prevent improper installation in non‑compatible panels and accepts copper or aluminum conductors sized from #14 to #4 AWG.
Mechanically, the BD3040 is a plug‑on mounted breaker, simplifying installation by allowing it to seat directly onto the panelboard bus without additional hardware. Eaton’s legacy Cutler‑Hammer design ensures long‑term reliability and broad compatibility with Type BR load centers for both new installations and replacements in maintenance scenarios. Its duplex configuration and UL 489 certification make it a versatile and space‑efficient choice for expanding circuit capacity while maintaining code‑compliant overcurrent protection in residential and light commercial electrical systems.
