What is the difference between circuit breakers

The operating time of the fuse is very less about 0. It is about 0. The mode of operation of the fuse is completely automatic, but circuit breakers can be operated manually as well as automatically with the help of a relay system.

The cost of the fuse is low, whereas circuit breakers are more costly. Leave a Comment Cancel Reply Your email address will not be published. Fuse works on the electrical and thermal properties of the conducting materials. Circuit breaker provides protection against power overloads and short circuits. This article is about the difference between fuses and circuit breakers and the advantages of each one of them over the other. Clearly, neither a fuse nor a circuit breaker can prevent the occurrence of faults.

Instead, they can prevent accidents and damage the equipment by interrupting the power supply to the equipment. Electric circuits are vulnerable to various kinds of faults out of which short circuits are the highly deleterious ones.

This is where circuit breakers and fuses do their job. Both do the same thing: interrupt the current flow to the circuit or equipment and safeguard the circuit from electrical hazards.

But their principle of operation and capabilities are different. Fuse is an electrical device that during short circuits and overloads, self-destructs and stops the current flow in a circuit. Circuit breakers are resettable circuit protection device that, on the occurrence of faults, it senses abnormal current flow and stops the current flow in a circuit.

During short circuits, the current flow in a circuit shall be several times its normal operational current. Circuit breakers and fuses sense these currents and at once interrupts the current flow. A fuse works based on the thermal property of materials conducting carrying electric current. It consists of a metal wire or conductor material that can conduct a predefined amount of current through it. Types of Thermistors and Applications. Close Search for.

Circuit Breaker is the combination of internal electromechanical switch and relay mechanism which interrupts the circuit in case of short circuit or overload.

The coil inside a Relay creates electromagnetic field while the solenoid as moving part known as armature opens and closes the contacts when coil is energized. Circuit Breaker provides interruption only. Faults detection is performed by relay inside circuit breaker.

Relay is a switching device that opens and closes the contacts electronically or electromechanically. Working Principle. Notify me of new posts by email. Electrical Technology 4 5 minutes read. Show More. Related Articles. Electric Bill Calculator with Examples.
