Schneider Electric BDA34100Y Three Phase Circuit Breaker

Schneider Electric’s PowerPact BDA34100Y is a 3-pole, 100 A molded‑case circuit breaker designed for 480Y/277 VAC three‑phase systems. As part of the PowerPact B frame, this unit uses I‑Line plug‑in mounting for straightforward installation in compatible Schneider Electric panels and delivers thermal‑magnetic protection with an 18 kA interrupting capacity at 480Y/277 VAC. It features long‑time and instantaneous trip functions (ABC phase connection) and load‑side mechanical lug terminals, making it well suited to protecting feeders and branch circuits in commercial and industrial distribution panels. Key specifications include: 3 poles, 100 A rating, 480Y/277 VAC, 18 kAIC interrupting capacity, I‑Line mounting, and compatibility with the BDA/PowerPact B family for reliable protection in demanding electrical environments. This compact protection device is commonly used to guard downstream equipment, motors, and electrical feeders within control panels, switchboards, and power distribution installations.
