WOT series 3 Pole 40A 63A 80A 100A 125A Load Isolator Switch

This series of disconnector is suitable for various applications. It can be used in motor control center, and is used for main switches in various equipments and machines. It provides a single pole to 8 pole switch, and can be equipped with a pistol handle or directly installed handle. It can be installed in the power distribution cabinet, and can provide side operation switch, wide distance switch and transfer switch, bypass switch, mechanical linkage and other combination switches.

* Load isolating switches are widely applied to distribution system and automation system in buildingpowerpetrochemical and other industries.

 

* The acceleration mechanism with instantaneous release of spring storage achieves fast connection or separation, which has nothing to do with the speed of operation handle, and greatly improves the ability of extinguishing arc.

 

* The shell made of glass fiber reinforced unsaturated polyester resin has good flame retardancy, dielectric properties, carbonization resistance and impact resistance.

 

* The parallel double breakpoint contact has self cleaning effect.

 

* All contact materials are copper plated silver alloy with two separate contact surfaces.

 

* The distance is large.

 

* In the "O" position, you can use three locks to lock the handle at the same time, and reliably avoid misoperation.

 

* The switch is beautiful, novel and concise, with small volume and complete function.
