The Square D FAP24100 circuit breaker is a rugged, 100-amp, 2-pole protection device engineered for 480V systems and bolt-on mounting. Built for maintenance, retrofit, and replacement projects, this unit delivers reliable overcurrent protection while delivering a secure mechanical fit in compatible panels.

Key specifications

• Amperage: 100 A
• Poles: 2-Pole
• Voltage: 480V
• Mounting: Bolt-On
• Part number: FAP24100

Why the bolt-on design matters

For industrial environments where vibration, panel temps, and long service life are a concern, bolt-on mounting provides a secure, vibration-resistant connection that stays tight over time. The FAP24100 is designed to align precisely with compatible Square D panels, simplifying installation and reducing the chance of misalignment during servicing or upgrades. This solid mounting approach helps minimize nuisance trips due to loose connections and supports reliable fault interruption when it’s needed most.

What problems this solves

• Reliable protection for 480V circuits in commercial or industrial panels, preventing overloads and short circuits from propagating through the system.
• A straightforward replacement option when upgrading or retrofitting to meet updated specs or panel requirements.
• Clear, referenceable compatibility via the precise part number (FAP24100), reducing guesswork during maintenance or stock management.

Ideal use cases

• Retrofit projects in 480V electrical rooms where a 100A, 2-pole breaker is required.
• Maintenance replacements in service panels or distribution panels that use bolt-on protection devices.
• Panel upgrades in manufacturing floors where durable mounting and dependable interruption are critical for uptime.

Installation and compatibility tips

Before ordering, confirm fit and ratings to ensure seamless replacement. The part number is the most reliable reference for compatibility with your panel family, so compare FAP24100 to your existing breaker model. When installing, follow standard lockout/tagout procedures, verify the system is de-energized, and ensure the panel is designed to accept bolt-on 2-pole 480V devices. If your application requires precise alignment or panel-specific adapters, plan for a quick check during the initial fitment.

Upgrade with confidence using the Square D FAP24100—a trusted solution for protecting 480V circuits with a secure, bolt-on installation that stands up to demanding industrial environments.
