FA24100AB - 100 Amp Circuit Breaker

FA24100AB - 100 Amp Circuit Breaker

When reliability and safety matter, the FA24100AB stands out. Made by Schneider Electric, this 2-pole, 100 Amp circuit breaker is built for serious performance in both commercial and industrial installations. Engineered for 480 V systems, it delivers dependable protection for a wide range of applications—from plant electrical rooms to HVAC systems to large residential panels. With its plug-in I-Line design and thermal-magnetic trip mechanism, you get swift protection against overloads and short-circuit events, and a design that helps keep maintenance and downtime to a minimum.

Key Features and Benefits

• Thermal-Magnetic Trip Unit: Combines long-time thermal protection for overloads with instantaneous magnetic tripping for fault currents—giving you a comprehensive safeguard for circuits under variable load conditions
• High Interrupting Capacity: Rated for 18 kA at 480 V (and 25 kA at 240 V), this breaker handles substantial fault currents without sacrificing protection or safety.
• I-Line Mounting System: The I-Line plug-in mounting allows for faster installation and easier replacement in compatible panelboards, helping reduce labor time.
• Versatile Load Conditions: With its AB-phase connection configuration and 100 A rating at 480 V, you’ll find this unit well suited for many single-phase installations in commercial and industrial settings.
