Schneider Electric BDA36080 I-Line Circuit Breaker

Schneider Electric's PowerPact B-Frame I-Line circuit breaker, model BDA36080, is a three-pole, 80 A molded-case unit designed for industrial power distribution. It uses thermal-magnetic protection with separate long-time and instantaneous trip functions, and it mounts on I-Line bus systems via plug-in ABC phase connections, with load-side mechanical lug terminals for field wiring. Rated for 600Y/347 VAC three-phase service, it also supports 480 VAC configurations with an interrupting rating of 18 kA at 480 VAC and 14 kA at 600 VAC, providing robust short-circuit protection for feeders, motors, and distribution panels. The device is part of Schneider Electric’s PowerPact B family and is specified as 80% rated for continuous operation, a common requirement in industrial installations, while maintaining a compact, modular form factor suitable for panelboard and switchboard assemblies.
