Westinghouse | MC3800F | Circuit Breaker | 800A | 3-Pole | 600V | 30kA | Bolt-On

The Westinghouse MC3800F circuit breaker is a purpose-built, bolt-on solution designed for demanding industrial panels where reliable high-current protection matters. With an 800A rating, a 3-pole configuration, and a 600V operating voltage, this unit delivers robust protection for large feeders, motor circuits, and critical distribution paths. Its 30kA short-circuit interrupting capability means it can safely shut down high-energy faults, helping minimize damage and downtime in busy electrical rooms and manufacturing environments.

Key specifications

• Amperage: 800A
• Poles: 3-Pole
• Voltage: 600V
• Interrupting rating: 30kA
• Mounting: Bolt-On
• Reference: Part number MC3800F

What makes this breaker stand out

• Secure bolt-on mounting provides a solid mechanical connection that stays put in vibration-prone or space-constrained panels, improving reliability over time.
• Three-phase protection for balanced load safety, ideal for large motors, conveyors, and multi-line feeders common in industrial settings.
• 600V rating aligns with typical industrial distribution systems, simplifying integration with existing gear and bus structures.
• 30kA interrupting capacity offers strong fault protection, reducing arc energy and safeguarding downstream equipment during fault events.
• Direct compatibility cue—use the MC3800F part number as the primary reference when selecting replacements or retrofits to ensure proper fit and ratings.

Ideal use cases

• Retrofit projects where an existing bolt-on, high-current breaker is in place and needs a like-for-like replacement to minimize panel rework.
• Maintenance and upgrades in industrial facilities with 600V distribution networks feeding motors, drives, and large loads.
• New-install simulations in legacy panels that require a proven, dependable 800A, 3-pole bolt-on solution.
• Emergency or fault-tolerance scenarios where a high interrupting capacity breaker helps protect wiring, bus bars, and downstream equipment.

Installation and practical considerations

• Ensure the panel design accepts bolt-on breakers of this size and that mounting hardware is compatible with your enclosure.
• Before ordering, verify fit and ratings against your existing system; the MC3800F part number is your best reference for compatibility.
• After installation, perform torque checks on mounting hardware and verify proper trip settings for your specific load profile.

Why it matters for your system

Choosing the Westinghouse MC3800F means investing in a proven, high-capacity protection device that aligns with industrial demands. Its combination of 800A capacity, three-phase coverage, strong fault interruption, and secure bolt-on installation translates to faster safety responses, reduced downtime, and longer life for panels and feeders in demanding environments. If you’re upgrading, replacing, or retrofitting a 600V, 3‑pole distribution feed, the MC3800F offers a direct, reliable path to safer, more resilient operation.
