Westinghouse | K3100 | Circuit Breaker | 100A | 3-Pole | 600V | 22kA | Bolt-On

Westinghouse K3100 Circuit Breaker is a robust, bolt-on protection solution for 3‑phase, 600V electrical systems. Designed for maintenance, retrofit, and replacement projects, this 100A, 3‑pole unit delivers reliable fault protection when exact specifications matter.

• Amperage: 100 A
• Poles: 3‑Pole
• Voltage rating: 600 V
• Interrupting capacity: 22 kA
• Mounting: Bolt-On
• Part reference: K3100

What makes this breaker stand out is its secure bolt‑on mounting, which provides a durable, field‑installable connection ideal for panels that require a fixed, reliable fit. With a 22kA interrupting capacity, it’s built to safely interrupt high fault currents in commercial and light industrial environments, giving you peace of mind during demanding operations.

Key use cases include three‑phase motor and equipment protection in 600V systems, panel modernization projects, and exact‑spec replacements where the panel or feeder circuits specify a 100A, 3‑pole, bolt‑on device. The K3100 family is a go‑to reference when matching panel labeling and compatibility is critical.

Fit and compatibility note: Confirm fit and ratings before ordering. The part number is the best reference to ensure this breaker matches your panel’s requirements and existing circuitry.

Practical tips for installation and best outcomes:

• Power down and lock out/tag out all related circuits before service or replacement.
• Verify panel labeling and ensure the slot technology supports bolt‑on, 3‑pole breakers of the K3100 family.
• Follow manufacturer torque recommendations and local electrical codes when securing mounting hardware.
• Use this unit in applications that demand solid 3‑phase protection for motors, compressors, and other heavy loads at 600V.
