AHA-08-20 CS Air Circuit Breakers, 800 ~ 2000 A

Product Description

Salient Features:

• Available in 3 or 4 pole for entire range
• Only 3 frame sizes in the entire range, 800A to 4000A, resulting in maximum interchangeability and minimum inventory of spares.
• High value of service breaking capacity, 50kA to 65kA, and making capacity, 105kA to 143kA at 415V AC
• Total breaking time less than 30ms (including arcing time of less than 10ms) & closing time of 40ms.
• Highest values of mechanical and electrical endurance due to robust mechanism design and special sintered metal contacts.
• Neutral pole (in 4 pole) closes early and opens later to prevent transient over voltages in loads connected between live and neutral lines.
• Most simple to operate and maintain.
• High dielectric strength even in hot and humid conditions due to use of class ‘B’ and ‘F’ insulating materials.
• Fibre glass safety shutter for safety of operating personnel.
• Tested for most onerous environmental conditions.
