1.What Is An Air Circuit Breakers?

An Air Circuit Breaker (ACB) is a core protection device used in low and medium-voltage power distribution systems.

When faults such as short circuits or overloads occur, ACBs utilize compressed air to rapidly extinguish the electric arc formed during contact separation, thereby automatically interrupting the fault current.

This operation effectively safeguards both upstream and downstream electrical equipment, while ensuring a stable power supply for industrial production, commercial facilities, and renewable energy projects.

Known for their high breaking capacity, operational reliability, ease of maintenance, flexible customization, and environmental advantages over oil-based alternatives, ACBs are widely adopted in power distribution systems across the globe.

2. What are the Types of Air Circuit Breakers?

Air Circuit Breakers used in power distribution are primarily classified into two types: withdraw-able and fixed.

CNTN Electric offers both types with superior quality and high reliability. You can send us inquiry for more information!

3.Как работают воздушные автоматические выключатели ？

ACBs operate by continuously monitoring circuit conditions through current-sensing components.

Integrating mechanical and electrical control logic, they enable normal circuit connection and disconnection, or rapidly cut off the current in the event of faults such as overload, short circuit, or under-voltage.

This ensures the safety of the power system and connected equipment.

4.Applications of Our High Quality ACB

As the main protection switch at the trunk line level in low-voltage power distribution systems, ACBs are ideal for applications that require high-current switching, reliable protection, and flexible operation and maintenance.

Key sectors include:

• Low-voltage power distribution systems,
• Industrial production – Power supply and protection for high-power equipment,
• Critical infrastructure – Ensuring highly reliable power supply
• Large commercial and civil buildings – Centralized power distribution and tiered protection,
• Renewable energy systems – Expanding protection for DC and low-voltage power distribution.,
