Rotary Knife Instrument Selector Switches

Rotary Knife Instrument Selector Switches

Applications

Rotary knife switches are mudular & compact in design and are very versatile for switching a.c. as well as d.c. resistive & inductive loads. They are used as Control switches in Control Panels and equipments such as MV & HV - Vaccum Circuit Breakers, Gas Circuit Breakers, On Load Tap Changers and Motor control panels. The switches are used as Mains switch or for instrument selector i.e. Ammeter selector & Voltmeter selector switches. These switches offer advantage of having quick make and break contacts for on load d.c. applications.

Features:

  •  Knife type of contacting making it suitable for switching on load d.c.
  •  Self cleaning of contacts is done during the operation.
  •  Modular design to achieve any number of poles with minimum components.
  •  Specially designed operator independent quick make/break mechanism.
  •  Superior insulating material ensures electricals & mechanical stability.

Specification:

  •  Conventional free AIr Thermal Current Rating (lth):16 Amp.
  •  Operational Voltage: 220 volts d.c.
  •  Operational Current: 6 Amp.
  •  Utilisation Category: DC13
  •  Switching capacity: Inductive loads with L/R ratio (time constant) of 20mS
  •  Dielectric Strength: 2.0 kv for 1 minute
  •  Insulation Resistance: > 500 Mohm
  •  Mechanical Durability: > 5, 00, 000 operations
  •  Electrical Durability: > 100, 000 operations
