Schneider Electric FA34030 I-Line Circuit Breaker

Schneider Electric's Square D FA34030 I-Line molded‑case circuit breaker is a 30‑amp, 3‑pole device built for 480 VAC three‑phase distribution in I‑Line panelboards. It delivers thermal‑magnetic protection and is rated for 80% continuous operation, making it suitable for circuits that carry load near the rated current. The FA34030 is part of the FA family and designed for I‑Line installations, with an official replacement option listing a PowerPact B 30 A, 3‑pole unit configured for 600Y/347 VAC and an interrupt rating around 14 kA to preserve I‑Line compatibility. This makes it a practical choice for 480 V branch‑circuit protection in industrial or commercial settings where compact, reliable protection is required for three‑phase equipment.
