FCL3100L | Circuit Breaker | 100A | 3-Pole | 480V

FCL3100L Circuit Breaker — a rugged industrial protection solution designed for reliable performance in 3‑phase, 480V power systems. With a 100A rating and a three-pole configuration, this breaker is purpose-built for maintenance, retrofit, and replacement projects where exact specifications matter.

• Amperage: 100A for protecting medium-sized industrial loads within 3‑phase distribution networks
• Poles: 3‑Pole design ensures synchronized interruption across all phases in a 480V system
• Voltage: 480V operating voltage aligns with common industrial and manufacturing environments
• Compatibility cue: The part number (FCL3100L) is the best reference for matching a like-for-like replacement
• Usage focus: Ideal for retrofit or replacement in panels and switchgear that require this exact specification

Who benefits most from the FCL3100L? engineers, maintenance technicians, and installers tasked with upgrading aging gear, expanding facilities, or standardizing protection across a 480V three-phase network. This breaker fits scenarios where a precise, known specification is critical to maintain system integrity and protection coordination.

Key use cases and scenarios

• Retrofit projects in manufacturing lines where existing equipment relies on a 100A, 3‑pole, 480V protection scheme
• Maintenance upgrades to improve reliability, trip response, and safety in 3‑phase distribution
• Replacement of legacy breakers that match the FCL3100L specification to minimize rework and compatibility issues
• New installations that require an exact 100A/3‑pole/480V configuration for consistent protection across panels

Practical buying tips

• Always confirm fit and ratings before ordering: use the part number FCL3100L as the primary compatibility reference
• Check panel documentation for mounting footprint and terminal compatibility to ensure a smooth retrofit
• Plan for compatibility with existing bus stabs and interlocks to maintain proper protection coordination
• If you’re coordinating multiple breakers, verify consistent trip characteristics and coordination with downstream protection devices

In demanding environments where reliability and precise protection are essential, the FCL3100L stands out as a focused, specification-driven choice. It delivers the exact 100A, 3‑pole, 480V protection you need for safe, continuous operation in your industrial electrical system.
