Westinghouse | MCA2800 | Circuit Breaker | 800A | 2-Pole | 600V

The Westinghouse MCA2800 Circuit Breaker is built for serious electrical protection in demanding environments. Designed as a robust 2-pole unit with an 800-amp capacity and 600-volt rating, it delivers reliable overcurrent protection for heavy feeders, main circuits, and critical equipment in industrial panels, retrofit projects, or service upgrades.

Key specifications at a glance

• Amperage: 800 A
• Poles: 2-Pole
• Voltage rating: 600 V
• Reference: Part number MCA2800 for compatibility checks

This breaker is ideal for maintenance, retrofit, and replacement scenarios where precise fit and ratings matter. When you’re upgrading an electrical system or restoring a panel to its intended protection level, the MCA2800 provides a straightforward, drop-in solution that aligns with Westinghouse engineering standards.

Why choose the MCA2800 for your system

• High-capacity protection: An 800 A rating supports large feeders and high-demand circuits, helping prevent nuisance trips while safeguarding wiring and connected equipment.
• Two-pole design for balanced protection: Simultaneous disconnection of both live conductors reduces arcing risk and ensures proper fault clearing in 600 V systems.
• Clear compatibility signals: The MCA2800 part number is the best reference for matching panels and components, simplifying cross-reference checks during procurement.
• Versatile applications: Well-suited for industrial panels, commercial electrical rooms, and retrofit projects where a reliable, high-ampere solution is required.

Practical use cases

• Upgrading service disconnects in manufacturing lines that run on 600 V and require strong protection against short circuits and overloads.
• Replacing aging or damaged breakers in heavy-use electrical panels where an 800 A, 2-pole unit is specified.
• Retrofitting legacy installations to meet current safety standards without overhauling the entire panel.

Installation and fit notes

Before ordering, confirm that your panel’s bus configuration and mounting style align with a 2-pole, 600 V Westinghouse MCA2800 unit. While the MCA2800 is designed for straightforward substitution in compatible systems, verifying the exact fit and ratings helps prevent compatibility challenges and ensures compliant operation once installed.

Who this is for

• Maintenance teams refreshing industrial control panels that demand high-current protection
• Retrofit projects replacing legacy breakers with a modern, reliable 800 A, 600 V solution
• Electrical engineers specifying a durable, high-capacity two-pole breaker for critical feeders

With the Westinghouse MCA2800, you’re choosing a trusted, purpose-built solution that delivers dependable protection, straightforward compatibility checks, and clear guidance for installation and maintenance. This is where long-term reliability meets practical, real-world electrical protection.
