Westinghouse 1A96651G Horizontal Mechanical Interlock

Description:

The Westinghouse Control WM16H Horizontal Mechanical Interlock Size 1-6 1A96651G is used in industrial motor control and electrical switching systems. Commonly installed in motor starters, contactor assemblies, and industrial control panels requiring mechanical interlocking between reversing or dual contactor configurations. Maintenance electricians, control engineers, and industrial automation technicians use this mechanical interlock kit for replacement, retrofit, or motor control system maintenance. The WM16H interlock is designed for NEMA Size 1 through Size 6 contactor applications and prevents simultaneous contactor engagement for safe electrical operation.

Applications:

The Westinghouse WM16H horizontal mechanical interlock is commonly used in industrial automation and motor control systems to mechanically prevent opposing contactors from energizing simultaneously. It is installed in reversing motor starters, conveyor systems, industrial machinery, and manufacturing control panels where reliable electrical interlocking and safe motor direction control are required.
