An Air Circuit Breaker (ACB) is an electrical protection device used to protect electrical circuits from overloads, short circuits, and faults in low-voltage power systems. It operates in air as the arc-extinguishing medium when the contacts of the breaker separate during fault conditions. ACBs are widely used in industrial, commercial, and residential applications where circuit protection is needed for low-voltage systems, typically ranging from 415V to 1 kV.

1. Arc Extinguishing in Air:

   • The arc is extinguished in air when the contacts of the ACB separate. In this process, the air between the contacts cools the arc, limiting the duration of the fault condition and ensuring that the circuit is safely disconnected.

2. Overload and Short-Circuit Protection:

   • ACBs are designed to protect circuits from overloads and short circuits. They automatically disconnect the circuit when the current exceeds a predefined threshold, preventing damage to electrical equipment and preventing potential fire hazards.

3. Manual and Automatic Operation:

   • ACBs can be operated manually or automatically. They feature a spring-loaded mechanism that trips when an overload or fault is detected, but they can also be operated manually by the operator for maintenance purposes.

4. Adjustable Trip Settings:

   • Many ACBs feature adjustable trip settings, allowing operators to set specific overload and short-circuit protection parameters based on the characteristics of the electrical circuit they are protecting. This flexibility allows them to be used in a variety of applications.

5. High Breaking Capacity:

   • Air Circuit Breakers are capable of interrupting high fault currents, making them suitable for industrial and commercial applications where large amounts of electrical power need to be controlled and protected.

6. Compact and Simple Design:

   • ACBs are typically designed to be compact and easy to install, making them ideal for use in distribution panels, switchgear, and motor control centers (MCCs). The simplicity of design allows for easy operation and maintenance.

An SF6 Circuit Breaker is a type of circuit breaker that uses sulfur hexafluoride (SF6) gas as an insulating and arc-extinguishing medium. SF6 circuit breakers are widely used in medium- and high-voltage electrical systems, particularly in switchgear for power transmission and distribution networks.

1. Arc Extinguishing Medium:

   • SF6 gas is used for arc quenching and insulating properties. When the circuit breaker opens to interrupt current, the SF6 gas helps to extinguish the arc formed between the contacts. SF6 has excellent dielectric strength, making it effective at isolating electrical components and quenching high-energy arcs.

2. High Dielectric Strength:

   • SF6 has a much higher dielectric strength compared to air and is able to withstand high voltages. This property makes SF6 circuit breakers suitable for use in high-voltage applications (typically above 72.5 kV).

3. Low Operating Temperature:

   • SF6 is chemically stable and has a low boiling point, which allows the circuit breaker to operate effectively in a wide range of temperatures. This makes it suitable for use in both hot and cold climates.

The APS Make 11KV Compact Circuit Breaker is a type of high-voltage electrical protection device used in medium-voltage power distribution systems, specifically designed for 11 kV (kilovolt) applications.
