Eaton BKFD100B 100A 3-Pole 480 V Circuit Breaker

The Eaton BKFD100B 100A 3-Pole 480 V Circuit Breaker is engineered to guard your three-phase power infrastructure with precise, reliable protection. Designed for 480 VAC systems, this unit delivers a robust 100 A rating in a compact, easy-to-integrate package that fits seamlessly into Eaton panels and compatible enclosures.

• Current rating: 100 A
• Poles: 3
• Voltage rating: 480 V
• Part number: BKFD100B

Why this matters for your operation: in a 3-phase, 480 V environment, the BKFD100B provides simultaneous disconnection of all three phases, helping to prevent arc faults and protect downstream equipment. With a dedicated three-pole design, it ensures coordinated shutoff for motors, conveyors, and other heavy loads, reducing the risk of partial power loss and improving overall system safety.

Ideal use cases include manufacturing floors, industrial facilities, data centers with three-phase gear, and HVAC systems that run on 480 V. If your installation relies on Eaton’s electrical distribution ecosystem, the BKFD100B offers straightforward integration, dependable performance, and consistent protection for feeders and branch circuits up to 100 amperes.

Practical considerations for installation and maintenance: verify panel compatibility with BKFD-series breakers, confirm busbar and mounting fit, and follow all local electrical codes during wiring, testing, and commissioning. Regularly inspect for wear or corrosion and replace with the BKFD100B to maintain optimal protection in your 3-phase network.

In short, the Eaton BKFD100B 100A 3-Pole 480 V Circuit Breaker is a purpose-built solution for reliable, clean protection in higher-voltage, three-phase systems, helping you safeguard critical loads while maintaining efficient, safe operation.
