Schneider Electric BDA36080 I-Line Circuit Breaker

Schneider Electric’s BDA36080 PowerPact B I-Line circuit breaker is a three-pole, 80 A molded‑case device designed for I‑Line bus assemblies in distribution panels. Rated for 600Y/347 VAC three‑phase service, it uses a thermal‑magnetic trip with long‑time and instantaneous trip functions and carries an 80% continuous‑load rating. Its interrupting capacity is 14 kA at 600Y/347 VAC, with a higher 18 kA rating at lower voltages such as 480 VAC, reflecting voltage‑dependent ratings in the PowerPact B catalog. The unit features plug‑on I‑Line mounting with ABC phase connections and load‑side mechanical lug terminals, and it is UL 489 listed as part of Schneider Electric’s PowerPact B family. This MCCB protects feeders, motors, and lighting circuits in commercial and light‑industrial panels where an I‑Line configuration is standard, offering a direct‑fit option for Schneider Electric panels built around the PowerPact B architecture.
