interrupting capacity "asco" #d03atsb30200ng0n, 1 each.
This new product is designed to provide users with years of safe and reliable service by combining a long life span in mechanical and electrical operation mode with high
interrupting capacity to provide selectivity and reduce hazards.
The
interrupting capacity from 25 to 150 kA allows a single unit to address multiple applications, which helps reduce product stocking.
A 65-kiloamp
interrupting capacity fault-current rating and testing to 160 kiloamps 8/20 ps per IEC 61643-1.
Interrupting capacity is the maximum fault current that can be repeatedly interrupted without failure of the breaker.
Improvements in the arc-interruption system, for example, increase
interrupting capacity and minimize space requirements.
4 kv of operating voltage, 20,000 of
interrupting capacity, rms amperes symmetrical at 24.
9 KV, 15,000 AMPS
INTERRUPTING CAPACITY, WITH NEMA HANGER.
