Spanner Required For Replied the Arcing Contracts. only 4 frame
Sizes for Entire Range (630A to 6300A), Resulting in Maximum
Interchangeability, Commonality of Parts and Minimum Inventory of
Spares. High Breaking Capacity, 50ka to 120ka and Making Capacity
From 105ka to 264ka with line or load connected to upper or loger
Terminals. High Speed Operating Mechanism Ensures a Total Opening
Time of 30ms (Including Arcing Time of Less than 10ms) and a Total
closing time of 40m sec. Neutral Pole of 4 POLE ACB is of Same
Current Rating as of 3 Pole. Highest Degree of System Protection
& Coordination Due to use of microprocessor base
Release. Due to use of tunsten-silver sintered metal contacts,
High Speed Opening Mechanism & Electromagnetic Instantaneous

　　INTRODUCTION1.3 High Breaking Capacity and Large Short time
Current Capacityby Fully Utilising Electromagnetic RepullSive Force,
a large short time current and high breaking capacity is
in our light and compact design. Light Contory Springs using to
ProVide Adequate Contract Pressure to Keep the Contract Temperature
Well with Limits and Also to Avoid Contact Bouncing. a Large
Short Circuit Current Cautromagnetic Repulsive force
Between The Contory Lead Halves. This Repulsive Force Works in A
Direction to Turn the Moving Contory CLOCKWISE About the Contory
shaft, giving it more contactal proportional to the short
Circuit Current. When interrupting a large carrent, the it
Electromagnetic Repulsive Force Works in a Direction to Sepa
The Moving Contory from the Stationary Contory. This. This.
Electromagnetic Repulsive force Adds to the Separating Force of
Trip Spring, Resulting in a High Speed Interruption.

　　1.3.1

　　Complete isolation of poles

　　All the poles are completely isolated from each other as well as
From Operating Mechanism by High Grade Insulating Materials. A.
Robust Design of Arc Chute in a Tempeature Resistant Moulded Body
And Fitted with Scientifically Shaped DEION-GRIDS, Totally
enCompaSses the Poles.
Through Arc Chute Which Clears and Cools The Highest Short
Circuit Arc Energy in LESS THAN 10ms.
Providing Highest Insulation Properties as well as breaking
CAPACITY.

　　1.3.2

　　High AC Dielectric withstand Voltage

　　Due to the user of non-hygroscopic, Glass Fibre Based Insulting
Materials and Corrugated Shape Employed for Better Creepage
Distance, The Ah Series Can withstand A Dielectric Voltage of 3.5KV
For a minute.

　　The Light and Compact ACBS in 4 Frame Sizes Not only help in
Standardising The Switchboard Design But Also Reduce the size of
load center.
