Answer 1

circut Iu What is the propose of of fuser and breakers in a system ? "Limit the Cursent in a Circuit Rount used for the protection Boeakers are Tusen and of Power system . case of The basic function is to break the circuit in the So as to protect the power Systery faulty Condition equipment and awxilliasien FUSE is low resistance device which is placed in when the circuit for protection. Under faulty Conditions desired value then due to the Current become more than the increase in temperature the far fuse fuse wire melts and breaks thus bre the Crant. breaking o Corcuit Breakers also solve same breaks the Circuit when the fault occurs. These are and in the power system. CB also has cabahility to se close after fault is th When System gets healthy propose le. it used for large rating
