What is the symbol for circuit breaker?
1200 A Identifies the drawout circuit breaker represented by the symbol as a 1200 ampere circuit breaker. 225 A/3P Indicates the fixed circuit breaker represented by the symbol as a 225 ampere, three-pole breaker. Indicates that the transformer represented by the symbol is connected delta-wye.
What is CKT breaker?
An Air Circuit Breaker (also known as an Air Blast Circuit Breaker or ACB) is an automatically operated electrical switch that uses air to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its primary function is to interrupt current flow after a fault is detected.
How many CKT breakers are there?
The three main types of circuit breakers are standard, GFCI and AFCI. Some models have dual functionality. Each handles different amp capacities and operates in different locations in the home.

What is VCB breaker?
A vacuum circuit breaker is a kind of circuit breaker where the arc quenching takes place in a vacuum medium. The operation of switching on and closing of current carrying contacts and interrelated arc interruption takes place in a vacuum chamber in the breaker which is called a vacuum interrupter.
What is air breaker switch?
An “air break switch’ is a switchgear device that uses air as the dielectric. Air Break Switches (ABS) are widely installed throughout distribution networks for use as both isolation or switching points. They are usually employed in outdoor installations.
What is the most common circuit breaker?
