Schneider Electric BDA34030Y I-Line Circuit Breaker

Schneider Electric BDA34030Y is a PowerPact B‑Frame molded‑case circuit breaker rated at 30 A and configured as a 3‑pole unit for 480Y/277 VAC systems, designed for I‑Line panelboard installations. It delivers an 18 kA interrupting capacity at 480Y/277 VAC (UL listed) and uses a thermal‑magnetic trip mechanism for both overload protection and short‑circuit protection. The device is 80% rated for continuous operation and is intended for feeder and branch‑circuit protection in commercial or light industrial power distribution. Typical applications include protecting 480Y/277 V feeders and circuits in electrical distribution panels where a compact, 3P MCCB with I‑Line mounting is required.
