Product Description

The 400A Pole Mounted Fuse Switch Disconnector is basically used for L.V. System and is designed as an on-load protective switch. The switch is used to provide a reliable medium for disconnection and protection of fully insulated open wire network section. It has a unique modular design and offers flexibility to connect switches for single, double, triple and quadruple phases. Series of such combinations can be linked together. The 400A Pole Mounted Fuse Switch Disconnector is a versatile and ideally suited for top mounting directly to poles, transformers and cross arms. It is fully insulated with high glass content. The upper housing of the switch is hinged to the lower body and houses the conductors, terminals and contacts.

  • Electrical and Mechanical fuse indicators and minimum number of moving parts.
  • Designed for switching on full load with DIN Type fuse links upto a rated current of 400A.
  • Arc quenching chambers to allow for On-Load switching.
  • Change of fuse possible by using the Insulated operating rod.
  • Lower flap can be withdrawn by the Insulated operating rod.
  • Flexibility of linking a series of flaps for simultaneous operation.
  • The contacts are rigidly mounted in the housing, independent of the terminal bolts.
  • Bolted or Moving blades linked neutral.
  • Host of termination available on request to suit individual Construction.
  • They are duly tin plated which ensures minimum contact resistance besides offering flexibility to use copper or aluminum cables. The switch can take conductor size of 50 to 240 sq. mm.
Type Testing:
The fuse switch has been extensively type tested according to IEC 60947 part 1 & 3 for:
  • Test Sequence 1: General Performance Characteristics.
  • Test Sequence 2: Electrical and Mechanical Endurance.
  • Test Sequence 3: Short Circuit Performance Capability
At 10 kA rms for 0.5 s:
  • Test Sequence 4: Conditional Short Circuit at 17 kA peak.
  • Test Sequence-5: Overload Performances, Degree of Protection and Impulse Test at 9.8 kV peak.
