Different types of circuit breakers and their ratings. Replace the panel s faceplate. Oil circuit breakers are high voltage circuit breakers that have their contacts immersed in oil. According different criteria there are different types of circuit breaker. Breakers are marked with either a slash or straight system voltage rating that indicates their capability to interrupt fault currents.

Most appliances have the amp rating listed on them. More on circuit breakers. The best suited type of mcb for domestic appliances where the current load is medium is type c. For complete specification standard ratings and various tests of switches and circuit breakers may be consulted.

Circuit breaker ratings the rating of the circuit breaker is given on the duties that are performed by it. Several breakers share one tank. Type d mcb has a high resistance as they can withstand up to 10 20 times the current rate. Let us discuss the different types of circuit breakers and their importance in detail.
