Australian Standard Circuit Breaker Sizes Chart Pdf

The Australian Standard Circuit Breaker Sizes Chart PDF is a document that provides information on the standard sizes of circuit breakers used in Australia. It is an essential reference for electrical engineers, designers, and contractors who need to specify the correct size of circuit breaker for a particular application.

The chart is divided into two sections: AC and DC. The AC section lists the standard sizes of circuit breakers for alternating current (AC) circuits, while the DC section lists the standard sizes of circuit breakers for direct current (DC) circuits.

Each section is further divided into three categories:

  • Miniature circuit breakers (MCBs)
  • Molded case circuit breakers (MCCBs)
  • Air circuit breakers (ACBs)

MCBs are the smallest type of circuit breaker and are typically used in residential and commercial applications. MCCBs are larger than MCBs and are typically used in industrial applications. ACBs are the largest type of circuit breaker and are typically used in high-voltage applications.

The chart provides the following information for each type of circuit breaker:

  • The nominal voltage rating
  • The current rating
  • The interrupting rating

The nominal voltage rating is the maximum voltage that the circuit breaker can withstand without tripping. The current rating is the maximum current that the circuit breaker can carry without tripping. The interrupting rating is the maximum current that the circuit breaker can interrupt without damage.

The Australian Standard Circuit Breaker Sizes Chart PDF is an essential reference for anyone who works with electrical circuits. It provides the information you need to select the correct size of circuit breaker for a particular application.
