Schneider Electric BDA34100Y U Circuit Breaker

Schneider Electric's PowerPact BDA34100Y U is a 100 A, 3-pole molded‑case circuit breaker (MCCB) designed for 480Y/277 VAC systems, providing robust protection for industrial and commercial power distribution. This B‑Frame, I‑Line style unit uses a thermal‑magnetic trip mechanism with plug‑in mounting and ABC phase connection, and it delivers an 18 kA interrupting rating at 480 VAC (18 kAIC). It is rated for 80% continuous operation, reflecting typical derating requirements for MCCBs in continuous service. Typical applications include protecting 3‑phase feeders to motor circuits, panelboards, and other power distribution equipment in industrial environments.
