Westinghouse MME 11-150 DC Electromagnetic Contactor

Description:

The Westinghouse MME 11-150 Contactor is a heavy-duty DC electromagnetic contactor designed for industrial motor control, battery switching, traction systems, and high-current direct current power applications. Commonly installed in crane systems, mining equipment, rail systems, DC motor drives, battery-powered machinery, and industrial automation equipment requiring reliable DC switching performance. Maintenance electricians, control engineers, and industrial automation technicians use this contactor for replacement, retrofit, or industrial power control maintenance. The MME series was developed for demanding industrial DC switching applications with rugged contact construction and magnetic arc suppression capability.

Applications:

The Westinghouse MME 11-150 contactor is commonly used in industrial electrical systems to switch DC motors, traction circuits, battery banks, and heavy-duty DC loads. It is installed in manufacturing facilities, material handling systems, mining machinery, industrial vehicles, and transportation equipment where dependable DC contact switching and stable electromagnetic control operation are required. The MME series has since been superseded by Eaton ME series DC contactors for modernization and replacement applications.
