Used and Refurbished Air Circuit Breakers

Air Circuit Breakers (ACB’s) use air to extinguish electrical sparks. When a fault occurs, these circuit breakers disrupt the circuit by releasing a burst of compressed air, extinguishing the arc. This isolates the defective section of the system, preventing damage. High-pressure air cools the electrical arc.

Inventory Selection of Air Circuit Breakers to Match and Replace Yours

Our inventory features a wide range of air circuit breaker types to match and replace your existing electrical equipment seamlessly, ensuring compatibility and optimal performance for different applications. Whether you need a specific voltage rating, current capacity, or unique design, we have options that suit your needs.

New and Refurbished Air Circuit Breakers -- It's Your Choice

We offer customers the flexibility to choose between new and refurbished ACB’s. New circuit breakers ensure the latest technology and warranties, while refurbished breakers provide cost-effective solutions without compromising quality, backed by thorough inspections and testing.

Electrical testing equipment Certifies Quality and Performance

Our products undergo rigorous electrical testing using the newest test equipment to guarantee quality, safety, and optimal performance. Each air circuit breaker is thoroughly inspected, ensuring it meets industry standards and specifications.

Specifications Based on Your Power Requirements

To specify the right air circuit breaker, consider power requirements such as voltage, current rating, breaking capacity, and the type of application. In most cases, air circuit breakers are used where there’s high risk of fire or explosion. Air Breakers are typically used for low voltages up to 15KV.

Our expert team can guide you through selecting the most suitable breaker for your specific power needs.

What Type of Air Circuit Breaker Do You Need?

Air Breaker Type

How the Breaker Type Works

Applications

Plain Break Air Breaker

Utilizes a pair of contacts within a chamber filled with air to interrupt the electrical circuit. When the contacts separate, an arc forms and is extinguished by the surrounding air.

Commonly used in low-voltage applications like residential and commercial settings, protecting against overcurrents and short circuits.

Magnetic Blowout Air Breaker

Uses a magnetic field to drive the arc away from the contacts, ensuring quick interruption and extinguishing of the arc. The magnetic force redirects the arc into a chute, effectively extinguishing it.

Often found in industrial and heavy-duty settings due to their capability to handle high fault currents, making them ideal for heavy machinery and large-scale equipment protection.

Air Chute Breaker

Uses a series of parallel plates to create a chute for the arc. When the contacts open, the arc is diverted into the chute, where it is elongated, cooled, and extinguished before being directed toward the exhaust vent.

Commonly applied in medium-voltage power distribution systems, particularly in substations, to protect transformers and other critical power equipment from faults and overloads.

Air Blast Breaker

Relies on a high-pressure air blast to extinguish the arc. The compressed air directed towards the arc causes rapid cooling and interruption, ensuring efficient breaking of the circuit.

Primarily utilized in high-voltage applications like power stations and critical infrastructure such as data centers and hospitals, offering reliable protection against high fault currents and maintaining system integrity.
