Eaton Westinghouse 11-300 15 A Breaker MCC Bucket 3P 240 V

Meet the Eaton – Westinghouse 11-300 Breaker MCC Bucket, engineered to power and protect industrial and commercial motor control systems. Built specifically for use with Eaton-Westinghouse 11-300 MCCs, this 15 A, 240 V breaker bucket delivers reliable, compact protection within a 6" vertical frame. Its three-pole configuration (3 P) makes it a solid choice for three-phase power distribution and motor control applications.

Key advantages

• Engineered for 11-300 MCCs: Designed to integrate seamlessly with Eaton-Westinghouse 11-300 motor control centers, ensuring dependable compatibility and easy incorporation into existing arrays.
• Compact, robust form factor: A 6" vertical frame optimizes space in crowded electrical rooms while maintaining sturdy construction for demanding environments.
• Reliable three-phase protection: 15 A current rating at 240 V (three-phase, 60 Hz) provides precise, dependable protection for motors and distribution circuits.
• Versatile use cases: Ideal for retrofit projects, OEM replacement, and custom MCC configurations, allowing you to modernize or expand your power distribution with minimal downtime.
• Industrial-grade reliability: Built to withstand the rigors of continuous operation in factory floors, manufacturing lines, and commercial facilities.

Who should consider this breaker MCC bucket?

• Facilities upgrading existing Eaton-Westinghouse 11-300 MCCs needing a compliant 15 A, 240 V breaker bucket.
• Engineers and electricians performing OEM replacements where precise fit and electrical characteristics matter.
• Maintenance teams planning retrofit projects to upgrade motor control centers without a full panel redesign.
• Systems designers building custom MCC configurations that require reliable, modular breaker components.

Use cases and practical scenarios

In an industrial plant with multiple conveyors and pumps, this breaker MCC bucket fits into an 11-300 frame to protect individual motor circuits from overloads while preserving clean power distribution. For OEM replacements, it streamlines replacement workflows by matching the original form factor and electrical specs, reducing commissioning time. In retrofits, it enables upgrading protection schemes or expanding capacity without reworking the entire MCC layout.
