Meet the Westinghouse NC21200 circuit breaker — a bolt-on, two-pole device rated for 600V and 1200A. Built for maintenance, retrofit, and replacement projects that demand exact specifications, this breaker keeps critical electrical systems protected with a precise fit and proven reliability.

Key specifications

• Amperage: 1200A
• Poles: 2-Pole
• Voltage: 600V
• Mounting: Bolt-On
• Reference: Part number NC21200 confirms compatibility

Why choose this Westinghouse NC21200? When your panel or equipment requires a bolt-on, two-pole breaker at 600V with a 1200A rating, this unit provides a precise match to the original design. Using the correct part ensures proper trip performance, alignment with terminals and bus connections, and safe operation, preserving protective coordination with downstream devices.

Ideal use cases

• Maintenance and replacement in industrial or commercial panels that specify NC21200 or Westinghouse bolt-on 2-pole 600V breakers
• Retrofit projects where upgrading protection without changing buswork or mounting footprint is required
• Spare part for legacy systems that rely on 1200A protection at 600V

Installation and compatibility tips

• Always confirm fit and ratings before ordering by cross-checking the panel documentation and the NC21200 reference.
• Ensure the panel accepts bolt-on mounting, two-pole breakers, and a 600V rating; verify terminal and bus connections align with the unit’s design.
• Follow standard electrical safety practices: de-energize equipment, use lockout/tagout procedures, and rely on qualified personnel for installation.
• Keep a spare NC21200 on hand for planned maintenance and quick replacements to minimize downtime.
• Store in a clean, dry environment to preserve contact surfaces and mounting hardware.

With the NC21200, you’re selecting a specialized Westinghouse breaker that aligns with legacy equipment and precise protection requirements. Its bolt-on design simplifies retrofits in compatible panels, helping you maintain system reliability with a component that matches your specifications exactly.
