This unit is purposefully suited for maintenance, retrofit, and replacement projects where exact specs matter, and it’s easy to identify by its FA3150L part number for compatibility checks.

Key specifications at a glance

• Amperage: 150A
• Poles: 3‑Pole
• Voltage rating: 600V
• Mounting: Bolt‑On
• Part number: FA3150L
• Best use: maintenance, retrofit, and replacement where exact match is required

Why the FA3150L stands out

• Secure bolt‑on mounting ensures a solid, high‑current connection in demanding panels, helping reduce the risk of loose contacts and arcing in critical 3‑phase circuits.
• Three‑pole design provides synchronized protection across all phases, essential for balanced loads and preventing phase imbalances in industrial or commercial setups.
• 600V compatibility aligns with standard distribution equipment used in many facilities, enabling reliable integration into existing electrical infrastructure.
• Exact matching reference is the FA3150L part number—use this as the primary compatibility check to ensure you’re ordering the right bolt‑on breaker for your panel.
• Focused use cases include panel upgrades, component replacements, and retrofits where preserving a specific protection profile is crucial for system reliability.

Ideal use scenarios

• Maintenance work on three‑phase panels that require a precise 150A, 3‑pole, 600V bolt‑on breaker.
• Retrofits or replacements in facilities where equipment protection and panel compatibility hinge on the FA3150L specification.
• Upgrades in commercial or light industrial environments where secure mounting and reliable trip performance are priorities.

Practical guidance for a smooth fit

Before ordering, confirm fit and ratings against your panel documentation. The FA3150L is best referenced by its part number to guarantee compatibility, especially when matching mounting style, pole configuration, and voltage requirements. If your project involves replacing an older bolt‑on breaker or aligning with a Westinghouse‑sourced system, this exact specification helps ensure minimal downtime and seamless operation.

With the Westinghouse FA3150L, you’re choosing a purpose‑driven, 3‑pole, 150A, 600V bolt‑on circuit breaker that’s built to support reliable power distribution in demanding environments. Its focused design and clear compatibility reference make it a precise, trustworthy choice for professional electrical maintenance and upgrades.
