Westinghouse | MA2600 | Circuit Breaker | 600A | 2-Pole | 600V | 30kA | Bolt-On

Meet the Westinghouse MA2600 Circuit Breaker—a purpose-built, two-pole protection device engineered for demanding 600V systems. With a 600A continuous rating and a formidable 30kA interrupting capacity, this bolt-on breaker is designed for maintenance, retrofit, and replacement projects where exact specifications matter. When you need dependable overcurrent protection that integrates cleanly into compatible panels, the MA2600 delivers.

Key specifications

• Amperage: 600 A
• Poles: 2-Pole
• Voltage: 600 V
• Interrupting rating: 30 kA
• Mounting: Bolt-On
• Part number: MA2600

Why this MA2600 stands out

The Westinghouse MA2600 is more than a spec sheet item—it's a deliberate choice for panels that require a proven bolt-on design with solid interrupting capacity. Its two-pole configuration protects both hot conductors, helping to ensure coordinated protection for feeders and branch circuits in 600V systems. The bolt-on mounting simplifies field installation and reduces panel downtime during upgrades or replacements, making it a practical option for service upgrades, data centers, industrial facilities, and commercial electrical rooms.

Ideal use cases

• Maintenance and retrofit of existing 600V electrical panels where a 600A, 2-pole breaker is required.
• Replacement for failed or aging MA2600 units in compatible panelboards, maintaining system protection without panel redesign.
• Upgrading distribution feeds in commercial or light industrial environments that operate near 600A load levels.
• Projects requiring a robust 30kA interrupting capacity to handle higher fault currents safely.

Installation, compatibility, and practical tips

Before ordering, verify fit and ratings against your panel catalog. The MA2600 is most reliably referenced by its part number, ensuring compatibility with bolt-on mounting schemes and 600V distribution setups. When planning installation, ensure that the panel directory, bus configuration, and enclosure clearances support a 2-pole, bolt-on device of this size. Keep spare mounting hardware and torque guidelines on hand to minimize downtime during replacement.

Compatibility reminder: The part number MA2600 is the best reference for ensuring a correct match with your panelboard. Confirm fit and ratings in your specific installation context to avoid surprises during replacement.
