ABB 226863K02 3-Pole Circuit Breaker

ABB 226863K02 3-Pole Circuit Breaker is a dependable, three‑pole protection solution engineered for modern three‑phase electrical systems. Designed by ABB, it integrates smoothly with existing ABB panels and configurations, delivering reliable interruption when faults occur across all three live conductors.

Why this 3‑pole model stands out is its focused approach to real‑world protection. It’s built to support continuous operation in demanding environments—from commercial facilities to light industrial settings—by providing coordinated disconnection during overloads or fault events. This helps minimize equipment wear, reduces downtime, and improves overall system safety.

Key advantages

• Three-pole protection for balanced three‑phase loads, ensuring all phases are isolated during a fault to prevent open‑phase conditions that can damage equipment.
• Direct compatibility with ABB installations through its exact part number (226863K02), making it a reliable replacement option in compatible panels without custom adapters.
• Durable construction designed to withstand repeated trip cycles and daily panel life in busy facilities.
• Clear, straightforward operation that supports predictable trips and easy maintenance planning for facility teams.

Ideal applications

This 3‑pole circuit breaker is well suited for three‑phase systems in HVAC controls, motor drives, conveyors, processing lines, and other commercial or light industrial equipment. It’s an excellent choice for panel builders and facilities managers who need a dependable ABB component that matches existing infrastructure and performance expectations.

Practical guidance for use

• Verify the device labeling for exact electrical ratings before installation and operation.
• Use as part of a comprehensive protection strategy to safeguard motors and three‑phase equipment from overloads and short circuits.
• Keep the replacement part consistent with ABB guidelines to maintain system compatibility and warranty coverage.
