Industrial FI3080L 80A 3-Pole 480 V Circuit Breaker

Introducing the Industrial FI3080L 80A 3-Pole 480 V Circuit Breaker—Part Number FI3080L—a rugged protection device built for demanding industrial power systems. This three-pole breaker is tailored for 480 V three-phase networks, delivering dependable overload protection across all phases to safeguard motors, feeders, and transformers from faults and electrical disturbances.

• 80 A current rating provides targeted protection for mid-to-large industrial equipment without frequent nuisance tripping during normal operation.
• 3-pole configuration ensures simultaneous disconnection of all three phases, preventing phase imbalance and reducing the risk of equipment damage.
• 480 V voltage rating aligns with common industrial distribution setups, simplifying panel design, installation, and part compatibility.
• Industrial-grade construction designed to withstand the rigors of harsh environments, including vibration, dust, and temperature variations often found in plants and warehouses.
• Efficient reset workflow after a fault, helping minimize downtime and keeping production lines up and running quickly.
• Clear part identity using the FI3080L designation makes replacement and maintenance straightforward within existing fleets.

Ideal use cases

• Protecting large 3-phase motors, pumps, conveyors, and processing equipment in manufacturing facilities and industrial plants.
• Feeder protection for distribution panels in warehouses, cold storage, and HVAC systems that run on 480 V three-phase power.
• Retrofit or upgrade projects where a standard, three-pole 480 V breaker is needed to maintain system safety and reliability.

Why this FI3080L design matters for your operation

In three-phase layouts, synchronized disconnection across all phases is critical to prevent partial faults from damaging equipment. The FI3080L delivers consistent protection for all three lines, reducing the likelihood of phase-to-phase faults and electrical fires. Its 80 A rating matches practical load profiles in many industrial feeders, balancing protection with operational continuity.

Installation and compatibility tips

• Verify that your panel and distribution system are rated for 480 V three-phase operation and that they accommodate a 3-pole FI3080L device.
• Ensure conductor sizing and wiring practices meet the amperage and enclosure requirements for safe, compliant installation.
• Use within standard industrial enclosures and follow proper lockout/tagout procedures when servicing or replacing the breaker.
• Maintain a spare FI3080L unit on hand for quick replacement and minimal downtime in critical production lines.

With the Industrial FI3080L 80A 3-Pole 480 V Circuit Breaker, you gain a reliable, purpose-built protection solution that fits into existing 3-phase infrastructures while delivering clear, actionable protection for your most important equipment. Part Number FI3080L ensures precise identification for maintenance and replacements, helping you keep your industrial power system safe and dependable.
