Westinghouse | EB3090 | Circuit Breaker | 90A | 3-Pole | 240V | 10kA | Bolt-On

Meet the Westinghouse EB3090 Circuit Breaker — a purpose-built 90A, 3-Pole, 240V bolt-on breaker designed for dependable protection in maintenance, retrofit, and replacement projects. With a robust 10kA interrupting rating, it’s ready to safely interrupt fault currents and keep your electrical system running smoothly.

• Amperage: 90A
• Poles: 3-Pole
• Voltage: 240V
• Interrupting Rating: 10kA
• Mounting: Bolt-On
• Part Number: EB3090

This breaker is an ideal fit for three-phase circuits that require solid protection at 240V. The bolt-on design provides a secure, field-serviceable mounting option, making it a practical choice for panel replacements or upgrades where matching specs is essential.

Why this matters: A 90A, 3-Pole configuration ensures all three phases disconnect together, improving safety and reducing arcing in high-load applications. The 10kA short-circuit rating gives you a higher level of protection against surge events, helping to safeguard equipment and wiring downstream.

Who it’s for: electricians and facilities technicians tackling maintenance, retrofit, or replacement projects in residential or light commercial panels that require a 90A, 3-Pole, 240V bolt-on breaker. It’s especially well-suited for upgrading existing panels to support larger loads or replacing older, failed breakers with a precise EB3090 match.

Important compatibility note: Confirm fit and ratings before ordering. The EB3090 part number is the best reference for compatibility, ensuring you select the exact bolt-on, 3-pole, 240V unit that matches your panel’s specifications.
