ELECTRONIC CIRCUIT BREAKER FOR OVERLOAD

2、PROTECTION P.Abirami，Merin Lizbeth George Abstract- This paper proposes an Electronic Circuit Breaker (ECB), trips the power supply instantaneously in overload condition Mechanically operated circuit breakers like MCB is based on very slow action thermal bimetal lever trip mechanism. The activation

3、time of MCB rely on the overloaded percentage of the fault. The concept of electronic circuit breaker is introduced to know that the thermally operated circuit breakers such as MCBs take longer time to trip. For sensitive loads it is necessary to activate the circuit breaker within the precised time

4、. The current flow through the series element is sensed by ECB and the corresponding voltage drop and the preset voltage is compared with a level comparator and the resultant signals are given to the microcontroller through a MOSFET which drives the relay to trip the load. Electronic circuit breaker

5、 is operated instantaneously with the tripping of relay. Keywords- Electronic Circuit Breaker, fast tripping time, overload I. INTRODUCTION Circuit breakers are electrical switches that are automatically activated to avoid damage to circuits which happens due to short circuits or overload. Miniature

6、 circuit breakers (MCB) carry out this function in specific applications 1. Its basic operation is to detect the fault current and interrupt the current flow. Unlike a fuse which must be replaced after one use. This type of circuit breakers are not economical when current rating exceed more than 1000 amps. The bimetallic strip present in such type wear as time passes on and the response become very slow. Changes in temperature diminishes the current capacity of the circuit breaker. MCBs r
