Westinghouse 1580206 Mechanical Interlock Assembly

Description:

The Westinghouse 1580206 Interlock, Section F-3 No. 33, is a mechanical interlock assembly designed for use with Westinghouse contactors, starters, and control equipment. This device prevents two electrically operated devices from being engaged simultaneously, providing safe sequencing and protection in reversing starter, transfer, and motor control applications. It is commonly found in legacy Westinghouse motor control systems where mechanical interlocking is required to prevent conflicting operations and equipment damage.

Applications:

The Westinghouse 1580206 interlock is commonly used in reversing motor starters, forward/reverse control circuits, transfer mechanisms, conveyor systems, pumps, compressors, and industrial machinery. It helps ensure that only one contactor or starter can operate at a time, protecting motors and control equipment from improper operation and mechanical stress.
