FA36100 - 100 Amp Circuit Breaker

FA36100 - 100 Amp Circuit Breaker

Upgrade your power distribution system with the FA36100 circuit breaker from Schneider Electric—a dependable solution engineered to safeguard high-current industrial and commercial systems. With a 100 A rating and thermal-magnetic trip technology, this 3-pole breaker gives precise protection against overloads and short-circuit events. Its I-Line mounting mode simplifies installation in a wide range of panels, while its high interrupt capacity ensures safe operation even under severe fault conditions.

Key Features and Benefits

• High Current Rating: Rated at 100 A, the FA36100 is designed to handle demanding loads in manufacturing plants, large commercial buildings or heavy-duty equipment environments.
• Thermal-Magnetic Trip Unit: Combines time-delayed thermal protection (for overloads) with magnetic instant tripping (for short-circuits), giving reliable fault-response performance.
• I-Line Mounting Mode: Allows secure plug-in installation into compatible I-Line panelboards, making retrofits and upgrades quick and straightforward.
• Exceptional Interrupt Capacity: Capable of interrupting up to 18 kA at 480 VAC and 25 kA at 240 VAC, delivering robust fault-handling margin and protecting your system with confidence.
• Durable Construction: Built by Schneider with quality materials and heavy-duty construction for long life and minimal maintenance in tough industrial settings.
