Westinghouse | NB2900 | Circuit Breaker | 900A | 2-Pole | 600V

Introducing the Westinghouse NB2900 circuit breaker—a high-capacity, two-pole protector built for demanding power systems. With a 900A rating and a 600V operating range, it delivers reliable, immediate isolation for large feeders and critical equipment. This device is ideal for maintenance, retrofit, and replacement projects where exact specifications matter, and NB2900 is the most reliable compatibility reference.

• Amperage: 900A
• Poles: 2-Pole
• Voltage: 600V
• Part Number: NB2900
• Brand: Westinghouse

Key differentiators and value:

• Precise compatibility: Use NB2900 as the primary reference to ensure it fits Westinghouse panels designed for this part number. Always confirm fit and ratings before ordering.
• High-current protection: Suited for heavy-load circuits typical in commercial and industrial environments, providing robust protection for important equipment.
• Dual-pole safety: The 2-pole configuration ensures both conductors disconnect together, enhancing safety during trips and maintenance.
• Retrofit-friendly: Designed to replace failing breakers in compatible panels without unnecessary modification, helping minimize downtime.

Practical use cases:

• Replacing a failed 900A, 2-pole, 600V breaker in an existing Westinghouse NB2900-compatible panel.
• Upgrading protection for high-demand feeders in industrial controls or distribution panels.
• Performing routine maintenance where exact NB2900 compatibility is required to maintain code-compliant protection.

How to ensure a perfect fit:

• Check your panel labeling and documentation to confirm NB2900 compatibility.
• Match the amperage (900A), number of poles (2), and system voltage (600V) with the panel’s specifications.
• Refer to the NB2900 part number as the primary reference for compatibility during purchase.
