Air Circuit Breaker (ACB)
Call for Price
An air circuit breaker (ACB), also known as an air blast circuit breaker, is an electrical switch that protects circuits from damage caused by excess current. ACBs are used in commercial and industrial environments, electrical power distribution, and contemporary electrical systems. They protect facilities and employees from increased electricity flow, and ensure that electrical systems are running efficiently and correctly.
ACBs operate using pressurized air and arc chutes to interrupt current flow after a fault is detected:
- Arc chutes: Redirect the arc into a controlled path, breaking it into smaller segments and lengthening its path
- Pressurized air: Pushes through the arc, disconnecting it from the contacts
ACBs can protect against faults such as: Overloads, Under voltages, Short circuits, and Earth faults.
ACBs can be used as the main circuit breaker of a ship, or as the master of a factory or building. Various accessories can be attached to an ACB depending on its purpose.
