MetalClad ChangeOver & Disconnector - Features
Switching Unit : Electrolytic copper for moving contact of switching unit
Mechanism : On load quick acting - quick make and break, mounted on separate plate and so II is not dependent on the box so lesser wear takes place and completely prevents hole enlargement as it happens if suported on sheet metal box. No hidarance to wiring

Box : Space, material, hinges, pres treatment for better adhesion of color for long listing life, powder coating, pvc gasket, totally dust and vermin proof, end plates with knock outs in higher ratings. Angled and polished handle

Safety: Mechanism, interlock and HV testing routine, provision for earthing, aqequate shielding to avoid accidental contack. Increased life of contact.
Provision of space for neutral link
Hardware - electroplated, Industrial spring washer (Avoids loosening due to vibration or jolts of continuous usage) and metric thread system ( for better gripping, contact area and torque application
Standard packing and labling
Approval IS:13947(III)
Acertain performance by testing : Low mV drop test, temperature rise, power loss, HV and insulation resistance test, mechanical and electrical endurance test and short circuit test.Switching unit and fuse are separable hence any one of them can be replaced. All the threads are provided on specially made nuts. The conventional process of providing the threads on the body is not reliable.
