Westinghouse | MA3600 | Circuit Breaker | 600A | 3-Pole | 600V | Bolt-On

Meet the Westinghouse MA3600 Circuit Breaker — a purpose-built solution for demanding electrical systems that require dependable overcurrent protection. With a 600A rating, 3-pole configuration, and 600V operating capability, this bolt-on breaker is engineered for robust performance in maintenance, retrofit, and replacement projects where exacting specifications matter.

• Amperage: 600A — designed to interrupt high-current faults and protect downstream equipment.
• Poles: 3-Pole — ideal for three-phase distribution, delivering synchronized protection across all phases.
• Voltage rating: 600V — suitable for common commercial and industrial power systems.
• Mounting: Bolt-On — provides a secure, rigid installation that aligns precisely with panel bus connections.
• Part reference: MA3600 — use this exact part number to verify compatibility and fit.

Why this MA3600 matters in your electrical system

The MA3600 isn’t just a breaker; it’s a precise fit for projects where compatibility matters as much as protection. Its bolt-on design simplifies installation and ensures a solid electrical connection, reducing the risk of loose mounting and contact failures. Designed for three-phase systems, it helps maintain balanced protection across all conductors, which is essential for equipment longevity and safe startup in industrial and commercial environments.

Where it shines

• Maintenance: Serve as a reliable spare or replacement in panels that specify MA3600-compatible breakers.
• Retrofit: Upgrade older panels that require a 3-pole, 600V, 600A bolt-on solution with a modern, trusted component.
• Replacement: Quick swap-in for systems that mandate exact part-number compatibility to maintain proper protection curves and trip characteristics.

Practical integration tips

• Always confirm fit and ratings against your panel documentation before ordering — the MA3600 is the best reference for compatibility.
• Verify your system voltage and three-phase configuration to ensure the 600V, 3-pole design matches your distribution equipment.
• During installation, ensure clean bus connections and proper torque on mounting hardware to maintain a reliable, long-term connection.

What to expect in real-world use

Organizations relying on steady, predictable protection in their electrical infrastructure will appreciate how the MA3600 sustains safe operation during fault events and minimizes downtime during service changes. This breaker is well suited for industrial machines, commercial power rooms, and any application where three-phase protection at 600V is required and a bolt-on mounting method is preferred.
