Applications

Drawer type Air Circuit Breakers are like a guard for electrical circuits. Under normal conditions, current flows through the closed contacts. When surge happens, like a short circuit, trips, and the contacts separate, creating an arc. Drawer type Air Circuit Breaker makes use of a strong air blast to extinguish the arc. It stops the current flow, protecting the circuit. It's like blowing out a candle flame to prevent a fire.

The key applications of air circuit breakers (ACBs) are as follows:

Low-Voltage Distribution: Protecting and controlling circuits in buildings, factories, and commercial spaces.
Motor Starting and Protection: Ensuring safe startup and operation of electric motors.
Power Plant Auxiliaries: Controlling and safeguarding equipment within power generation facilities.
High-Risk Environments: ACBs are preferred in areas with fire hazards due to their fast arc quenching capability.
Frequent Operation: Their robust design makes them suitable for applications requiring frequent switching.
Mounting mode：Fixed and Draw-out Type
