FCL34100 - 100 Amp Circuit Breaker

FCL34100 - 100 Amp Circuit Breaker

When you require top-tier protection for heavy commercial and industrial power systems, the FCL34100 offers dependable performance built to handle demanding conditions. This 100-amp, 3-pole molded-case circuit breaker is designed for rigorous use—featuring an interrupting capacity of 65 kA at 480 VAC and 100 kA at 240 VAC—so you can rest assured it will respond when faults occur, safeguarding your electrical infrastructure. With a thermal-magnetic trip unit incorporated into a durable frame, it provides consistent protection against both overloads and short-circuit events. Whether it’s installed in a panelboard, switchboard, motor control center or industrial enclosure, the FCL34100 is up to the challenge. The HACR rating also means it’s HVAC-system-ready, integrating easily into climatic control systems without requiring specialized breakers.

Key Features and Benefits

• High interrupting capacity: Handles up to 65 kA at 480 VAC and 100 kA at 240 VAC—so it’s ready to protect high-energy systems from destructive fault currents.
• Reliable thermal-magnetic trip technology: Gives you accurate protection against overloads and short circuits, reducing downtime and maintenance.
• Versatile usage: Works across panelboards, switchboards, motor control centers and industrial enclosures—so you don’t need multiple breaker types for different locations.
• HACR (Heating, Air-Conditioning & Refrigeration) rated: Provides assurance that it meets HVAC sector demands, so you can deploy it confidently in climate-control installations.
• Heavy-duty build: Designed to stand up to industrial environments with consistent performance in rigorous conditions.
