FA34080 **Old Style** 80 Amp Circuit Breaker

FA34080 **Old Style** 80 Amp Circuit Breaker

Introducing the FA34080 80 A I-Line Molded-Case Circuit Breaker, a high-performance 3-pole solution from Square D by Schneider Electric, designed for demanding commercial and industrial electrical systems. With a 480 V rating and 80 A current capacity, this breaker offers dependable overload and short-circuit protection by combining an I-Line plug-in mounting system with a thermal-magnetic trip unit. Whether deployed in distribution panels, motor-control applications, or HVAC systems, the FA34080 delivers assurance-worthy performance, space-efficient design, and a streamlined installation process.

Key Features and Benefits

• Precise protection: Built with a thermal-magnetic trip mechanism, the FA34080 responds quickly to overcurrents and short-circuit events, helping safeguard equipment and prevent downtime.
• Efficient installation: The I-Line plug-in mounting system simplifies panel integration, allowing for faster setup and minimal disruption when upgrading or replacing units.
• Space-optimized design: Measuring approximately 6.4 in (H) × 4.5 in (W) × 4.13 in (D), this breaker fits neatly into electrical panels where space is at a premium.
• Durable construction: Engineered using quality materials and designed for demanding electrical environments, the FA34080 is built to last and support long-term system reliability.
• High interrupting capability: With an 18 kA interrupt rating at 480 V AC and up to 25 kA at 240 V AC (per manufacturer data), it stands ready for serious protection scenarios.
