Understanding the Difference Between ACB and VCB Breakers

Circuit breakers are an important aspect in the electrical system world regarding safety and power distribution. Among all kinds, ACBs (Air Circuit Breakers) and VCBs (Vacuum Circuit Breakers) are the most common for medium to high voltages. Being one of the leading Siemens supplier in Qatar, AMPS Electric Trading is more than happy to provide quality Siemens ACBs and VCBs for multiple industrial applications. This blog focuses on the major differences between ACBs and VCBs, merits of usage, applications, and how Siemens products lead in the market.

What Are ACB and VCB Breakers?

Air Circuit Breaker (ACB)

An Air Circuit Breaker works by breaking the current in an air medium. Air circuit breakers are normally employed for low-voltage applications up to 690V and have a proven history of being reliable for overloads, short circuits, and ground faults. In the arc generated during interruption, it is extinguished in an arc chute, which makes air circuit breakers useful for industrial, commercial, and residential environments.

Vacuum Circuit Breaker (VCB)

A VCB interrupts flow of electricity through the medium of creating vacuum within arc chamber. The VCBs are especially for medium-to-high voltage rating applications, from 3.3 kV to 33 kV. Therefore, the vacuum breaks the arc effectively and thereby reduces most of the wear and tear, which provides a reliable operation with the least extent of maintenance requirements.

Key Differences Between ACB and VCB Breakers

There are many differences within Air Circuit Breakers and Vacuum Circuit Breakers. ACBs work on principles where air is used as the arc extinguishing medium and are used in LV applications, up to a voltage of 690 V. They make use of arc chutes to interrupt the flow of electricity in case of faults. On the other hand, VCBs make use of vacuum interrupters for arc extinction; therefore, they are ideally suited for medium to high voltage applications from 3.3kV to 33kV. VCBs are more robust and compact with minimal maintenance while ACBs may require routine maintenance. Furthermore, ACBs are relatively cheaper to purchase, but VCBs have a lower life cycle cost due to their efficiency and longer lifespan.
