Westinghouse RFA3090L Circuit Breaker — 90A, 3-Pole, 600V

The Westinghouse RFA3090L Circuit Breaker is a purpose-built protection device designed for 3-phase electrical systems. With a 90 amp rating, a 3-pole configuration, and a 600V maximum, this breaker is engineered to safeguard heavy-duty circuits in commercial and industrial environments while simplifying maintenance, retrofit, and replacement projects.

Key specifications

• Amperage: 90 A
• Poles: 3-Pole
• Voltage: 600 V
• Part number: RFA3090L
• Recommended use: maintenance, retrofit, and replacement where matching specs are required

Why this model stands out

Designed for reliability in demanding setups, the RFA3090L delivers precise overcurrent protection for three-phase circuits. The 3-pole configuration ensures coordinated interruption across all hot legs, helping to minimize arc flash risk and protect connected equipment from a single-point failure. This isn’t a generic swap—it’s a targeted solution that aligns with existing panel layouts that require a 90A, 3-pole, 600V specification.

Ideal use cases

• Retrofit projects where a matching 90A, 3-pole, 600V breaker is needed to restore or upgrade protection
• Maintenance replacements to quickly restore circuit safety without altering panel configuration
• New or improved installations in commercial/industrial electrical systems operating at up to 600V

Compatibility and ordering tips

Before ordering, verify fit and ratings against your panel’s labeling. The part number is the most reliable reference for compatibility. If your system lists RFA3090L or requires a 90A, 3-pole, 600V breaker, this Westinghouse model is designed to meet those precise specs and integrate smoothly with compatible equipment.

Practical guidance for install and use

Plan for proper torque on connections and ensure conductor sizing aligns with 90A protection. Keep a maintenance checklist handy: confirm labeling, inspect for any signs of wear, and match the protection strategy to the connected load. With the RFA3090L installed, you gain predictable protection timing and reliable performance across your 3-phase system.
