Westinghouse | MA2800S | Circuit Breaker | 800A | 2-Pole | 600V | Bolt-On

When systems demand dependable, high-current protection, the Westinghouse MA2800S Circuit Breaker delivers. This 800A, 2-pole, 600V bolt-on breaker is designed for maintenance, retrofit, and replacement in compatible panels, providing a trusted solution for critical feeders.

Key specifications you’ll rely on:

• Amperage: 800A
• Poles: 2-Pole (two hot legs disconnect together)
• Voltage rating: 600V
• Mounting type: Bolt-On, for direct panel mounting
• Reference: Part number MA2800S is the best compatibility reference

Why this matters in real-world use:

• High-current protection for main feeders and critical circuits in industrial or commercial distribution panels.
• Two-pole design ensures simultaneous disconnection of both live conductors, reducing arc exposure during fault conditions.
• Bolt-on mounting provides a secure, durable connection in panels that require direct terminal hardware, enhancing reliability in vibration-prone environments.
• Ideal for retrofit projects where the existing equipment calls for MA-series bolt-on breakers or where replacement parts must match exact electrical ratings.

Practical guidance for selection and installation:

• Always confirm fit and ratings before ordering—the MA2800S is the definitive reference for compatibility in compatible Westinghouse panels. Check your panel labeling or consult the equipment's service manual to ensure a bolt-on 2-pole 800A, 600V breaker is appropriate.
• Because this is a high-current device, ensure all safety protocols are followed and that installation is performed by a qualified electrician with the panel de-energized and properly grounded.
• Keep in mind that mounting hardware and bus connections must match the panel’s design for bolt-on breakers; deviations can affect performance and safety.

With the MA2800S, you get a purpose-built solution that aligns with existing Westinghouse electrical infrastructure, reduces downtime during service windows, and helps maintain reliable power distribution across demanding loads.
