NRT-EL 3,6/3600 - outdoor traction switch disconnector
Application:
One – pole outdoor traction LBS NRT – EL 3,6/3600 is designed for opening and closing electric circuits, conducting of direct and short circuit currents and performing switching operations in the current range which does not exceed the maximum rated current of the switch.
Advantages:
- high rated current
- silver plated contacts
- high resistance to weather conditions
- in open position it creates visible and safe isolating clearance
- compliance with the standard PN-EN 50123-4:2000E
Construction:
Switch disconnector includes steel basis (rigid and mobile), copper busbars, contacts, outdoor insulators, arcing horns providing arc suppression. The copper parts are silver plated, the steel parts are zinc plated, and the connecting parts are made of stainless steel. The device opens by connecting the lever with the motor drive with the aid of string.
