Protection and Automation
Air Circuit Breaker (ACB):
Function: Protection and control of electrical machinaries against overloads, short-circuits and ground fault protection (Optional).
Application : The Air circuit breakers are used in industrial low voltage plants for currents from 800A to 6300A. They are used in switchgear and and for protection for motors, generators, capacitors etc. They are also used in auto transfer switch (ATS) and generator synchronising panel.
