Westinghouse | RF3090 | Circuit Breaker | 90A | 3-Pole | 600V

Westinghouse RF3090 Circuit Breaker is a robust three-pole protection device engineered for modern electrical distributions. With a 90A rating and a 600V maximum, it's built to safely interrupt and protect three-phase feeders and motor circuits in industrial and commercial settings.

Key specifications at a glance:

• Amperage: 90A
• Poles: 3-Pole
• Voltage: 600V
• Part number: RF3090

Why this matters for your project:

• Exact compatibility: The RF3090 part number is the best reference for replacement or retrofit projects. Always confirm fit by matching the panel label, bus configuration, and system voltage before ordering.
• Reliable three-phase protection: 3-pole design ensures simultaneous interruption across all three phases, reducing arcing risk and protecting equipment from phase-to-phase faults.
• Simple retrofit option: Designed to slot into panels and raceways that previously housed a like-for-like Westinghouse unit, minimizing downtime during maintenance or upgrades.

Ideal use scenarios:

• Replacement in existing 3-phase, 600V distribution panels where a 90A trip rating is appropriate
• Retrofit projects updating older equipment to current safety standards
• Backup protection for three-phase motor feeders in manufacturing lines, HVAC systems, and processing equipment

Practical considerations:

• Always verify fit and ratings against your panel’s labeling and the equipment's electrical requirements. The RF3090 should be used when the panel expects a 90A, 3-pole, 600V circuit breaker.
• Keep a spare RF3090 on hand for quick replacements, reducing downtime during routine maintenance or fault events.
• Follow all electrical codes and install by a qualified technician to ensure proper mounting, termination, and safety clearances.

With Westinghouse's legacy of dependable protection, the RF3090 delivers predictable performance and a straightforward, like-for-like replacement path for complex three-phase systems. When your operation depends on reliable power distribution, choose the RF3090 to align with your existing infrastructure and keep critical equipment safeguarded.
