Westinghouse 100AMPS - 100A, 3-Pole, Circuit Breaker

Introducing the Westinghouse 100AMPS — a reliable 100A, 3-Pole circuit breaker built to uphold safety and continuity in demanding electrical environments. Designed for panelboards, switchboards, and control panels, this breaker delivers solid overcurrent protection where it matters most, making it a smart choice for industrial, commercial, and OEM applications.

• Three-pole configuration protects all three phases together, ensuring balanced operation in 3‑phase circuits and simplifying integration with motor feeders and multi‑phase equipment.
• 100A current rating suited for main feeders, distribution circuits, and motor control applications that draw up to 100 amperes, providing decisive protection without unnecessary trips.
• Versatile mounting compatible with standard panelboards, switchboards, and control panels, enabling streamlined upgrades and reliable installation in existing cabinets.
• Rugged, mission-ready construction designed for the rigors of industrial and commercial environments, delivering dependable performance in everyday operations.
• OEM-friendly utility fits into equipment builds and custom control solutions, helping engineers and installers meet exacting protection requirements.

Who benefits most

This breaker is ideal for facilities and projects where dependable protection and safe operation are non-negotiable. Use it in motor control centers, distribution panels, and control enclosures where three-phase power drives equipment such as pumps, compressors, conveyors, and HVAC systems. It also serves as a robust main or feeder protection device in OEM equipment and custom control solutions.

Key advantages in real-world use

• Reduces risk of damage from overcurrent events across three power lines, helping protect downstream equipment and wiring.
• Optimizes panel organization by supplying a single, clear protection point for three-phase circuits.
• Supports safer maintenance and faster troubleshooting by providing clear, centralized protection in the control architecture.

Practical installation and care tips

• Verify panel compatibility and ensure the 3-pole device aligns with your bus bar configuration and mounting provisions.
• Confirm the 100A rating matches the circuit requirements and that upstream protection and downstream conductors are sized accordingly.
• Follow panel manufacturer torque recommendations for all securing connections and ensure clean, corrosion-free terminations.
• Regularly inspect for signs of wear or overheating in high-use environments and replace after any trip events or observed degradation.
