Schneider Electric BJA36040 I Line Take Out Switch

Schneider Electric's Square D PowerPact B-Frame BJA36040 is a 3‑pole, 40‑amp circuit breaker designed for I‑Line bus installations in industrial and commercial power distribution. This thermal‑magnetic device protects feeders and branch circuits against overload and short circuits on a 600Y/347 VAC system, with interrupting ratings of 25 kA at 600Y/347 VAC, 65 kA at 480 VAC, and 100 kA at 240 VAC. It features I‑Line mounting with the ON end configured for I‑Line and the OFF end provided with mechanical lugs, aligning with plug‑in bus arrangements used in Square D panels. The BJA36040 is UL Listed, CSA Certified, and IEC Rated, ensuring compliance with common safety standards. The unit is rated for 40 A continuous operation and, as part of the PowerPact B family, shares standardized trip characteristics across the range, including a magnetic trip range with a hold of 400 A and a trip at 600 A, depending on system conditions. This makes it suitable as a service disconnect or feeder protection in installations where a 3‑phase, 40‑amp protective device is required and I‑Line compatibility is essential.
