Westinghouse | MS360800A | Circuit Breaker | 800A | 3-Pole | 600V | 30kA

Engineered for reliability in industrial power distribution, the Westinghouse MS360800A Circuit Breaker is a 3-pole device designed to protect three-phase systems up to 600 volts with an 800 amp rating and a 30kA interrupting capacity. This model is specifically identified by part number MS360800A, making it an exact-fit choice for maintenance, retrofit, or replacement projects where compatibility matters.

Key benefits

• Exact-fit compatibility: The MS360800A part number is the most reliable reference for matching your panel or switchgear.
• High-current protection: 800A rated continuous current to safely feed large motor loads and distribution circuits.
• Three-phase reliability: 3-pole design handles synchronized protection across all three hot legs.
• Broad voltage tolerance: Suitable for 600V systems, common in industrial settings.
• Robust interrupting capacity: 30kA short-circuit rating provides strong fault clearance, reducing damage risk.

Ideal use cases

Use this breaker for maintenance and retrofit projects in industrial power distributions, motor control centers, and switchgear assemblies where an 800A, 3-pole, 600V protection device is required. It’s well-suited for feeders that power heavy machinery, conveyors, pumps, and processing lines that demand reliable overload protection with quick fault interruption.

Why this matters

Choosing the Westinghouse MS360800A ensures you’re deploying a trusted, purpose-built component with a proven track record in electrical protection. The combination of high current capacity, three-phase coverage, and a solid 30kA interrupting rating translates into shorter downtime during faults and safer system operation for your crew.

Important compatibility note

Before ordering, confirm fit and ratings against your existing hardware. The part number MS360800A is the best reference to ensure mechanical fit and electrical compatibility in your panel, bus arrangement, and overall protection scheme.

Practical tips for installation and maintenance

• Keep a record of the exact part number (MS360800A) for future replacements or retrofits to avoid mismatches.
• Plan for future expansion by selecting a breaker with the same three-pole configuration and voltage rating.
• Store spare units in a clean, dry environment to prevent corrosion of terminals and contacts.
