  Three-Pole   Load Break Switches:
 

ABS Load Break Switches and Isolators for voltages ranging from 3.3kv to 36 kv offers a high technical standard and economy over the years for the switchgear manufacture with dependability, reliabilty and versatility.

   
  Main Features:
     
  • High Operating reliability
• Simple maintenance and inspection
• High dynamic & thermal strength
• Tested in CPRI as per IS-9920 (= IEC 265)
• Special tubular arc-chutes
• Current interruption without visible arcs.
• Simple driving
• mechanism
   
  Triple Pole Load Break Switch:
xxx  

he salient feature of ABS Load Break Switch is its ability to permit load connections even under a short circuit condition without danger to the operating personnel. It complies with IEC, VDE, & IS standards. A high speed(snap action) make and break ensures a fast switching action and the very special design of arc chutes having excellent extinguishing properties for both high and low currents, suitability of mounting in horizontal or vertical plane etc. prove the versatility of these switches.

   
  Off-Load Isolator:
 
     

Due to the compact design of individual cubicles, and the feasibility of mounting the switches in different directions, economy in space is achieved , with ample scope for future extension. The triple pole load break switch can be used for switching of transformer feeders, overhead lines, capacitor banks, cable feeders, and ring mains. For protection against circuits H.T.Fuses can be offered with the switch.
