Product snapshot

• Current rating: 100 A
• Poles: 3
• Voltage rating: 690 V
• Part number: FWF3100KL
• Product type: Industrial Circuit Breaker

The FWF3100KL is purpose-built for three-phase distribution, ensuring that all three phases trip together to prevent unsafe partial faults. Its 690 V rating makes it suitable for high-voltage industrial networks, providing reliable protection where standard low-voltage breakers simply can’t accommodate the load or voltage levels common in modern manufacturing environments.

Why this model stands out

• Three-pole coordination: Simultaneous disconnection of all phases minimizes fault conditions and simplifies safe recovery after a trip.
• High-voltage capability: 690 V rating supports contemporary industrial power schemes, reducing the need for multiple device substitutions when upgrading facilities.
• Clear protection for critical equipment: Ideal for safeguarding motors, variable-frequency drives, conveyor systems, and other three-phase loads from overloads and short circuits.

Who benefits most from the FWF3100KL? electrical engineers, panel builders, and facility managers who design and maintain three-phase distribution networks in warehouses, manufacturing lines, and processing plants. If you’re wiring or upgrading a high-voltage, three-phase feeder, this breaker provides the essential protection you need without compromising on performance or reliability.

Practical usage tips:

• Match the FWF3100KL to your panelboard or switchgear’s mounting and wiring specifications to ensure proper fit and compliance with electrical codes.
• Consult the equipment’s wiring diagrams and safety guidelines to determine the appropriate interrupting capacity for your fault scenarios.
• Use this breaker in applications where uninterrupted three-phase protection is critical for maintaining uptime and safeguarding expensive machinery.

For facilities seeking dependable, three-phase protection at high voltage, the FWF3100KL 100A 3-Pole 690 V Circuit Breaker delivers precise performance with a focused, application-driven design. Add this component to your industrial electrical setup and rely on robust fault interruption to keep systems protected and productive.
