Eaton T0-4-8410/I1 3-Pole ON-OFF Toggle Switch, 20 A, Front Mount, Black/White 207140

Industrial and commercial electrical installations often require a robust, front-mounted switch that can reliably control three-phase circuits while withstanding harsh environments. The Eaton T0-4-8410/I1 toggle switch solves this by providing a 3-pole ON-OFF switching function in a compact design, ensuring safe and efficient operation for machinery and control panels.

Who is it for

This switch is intended for electricians, panel builders, and maintenance technicians who need a dependable, manually operated disconnect or control switch for three-phase loads. It is suitable for use in industrial control systems, HVAC equipment, and power distribution units where front mounting and clear visual status indication are required.
