Triple pole and double pole symbol for circuit breaker. MCB can be reset very fast and don’t have any maintenance cost. When it comes to house wiring applications, MCB is the most preferred choice for overload and short circuit protection. Handling MCB is quite safer and it quickly restores the supply. The MCB is an electromechanical device that guards the electric wires and electrical appliances against overcurrent so as to avoid any kind of fire or electrical hazards. It automatically switches OFF electrical circuits during any abnormal condition in the electrical network such as overload and short circuit conditions.

MCB stands for Miniature Circuit Breaker. With a current rating of up to 2500A.MCCBs are used instead of miniature circuit breakers (MCBs) in large scale power systems for system isolation and protection purposes. Once the fault occurs within the system, the circuit breaker contacts will be separated and the arc will be struck between the contacts.Ī moulded case circuit breaker (MCCB) is a type of electrical protection device that is used to protect the electrical circuit from excessive current, which can cause overload or a short circuit. MCB,MCCB and OCB oil circuit breaker.Īn oil circuit breaker is a type of circuit breaker that uses insulating oil as an arc quenching medium. Now that you know why circuit symbols are used, let us dive into a look at some circuit symbols for circuit breakers.

The use of circuit symbols makes it easy for engineers, technologist technicians and craftsmen from different parts of the world to collaborate, communicate and share ideas.

Circuit symbols make it easy to understand complex designs.

make it easy to make electrical and electronics drawings.

But if he knows how to interpret circuit symbols, I will communicate effectively with him. I may have a colleague who does not speak my local language. When they make some observations they communicate back to you.Ĭircuit symbols are a universal way of communicating. Many are the times that you would like to share notes with your colleagues. In engineering, when you want to make a car or an electrical machine.

In short, a circuit symbol is a language that is used in engineering to communicate. Final thoughts on the symbol for circuit breaker.Ĭircuit symbols make communication easy.Cartrige and Isolator symbol for circuit breaker.Triple pole and double pole symbol for circuit breaker.
