Circuit breaker - Wikipedia

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect low-current circuits or individual household applGet price

LPG Leakage Detection Circuit Breaker Using RF Module

LPG Has A Dangerous Characteristics That Can Be Considered, TheStatement of The ProblemSignificance of The StudyAnother Related Project Paper to This Project Is Design andin This Project The Microcontroller Is Used as The Software Programs toThe Transmitted Data Is Received by An RF Receiver Operating at TheEncoder & RF TransmitterThe toxicity, LPG gas even though slightly toxic, is not poisonous it can pose a serious effect if they leak, it may leak as a gas or a liquid. If the liquid leaks it will quickly evaporate and form a relatively large cloud of gas which will drop to the ground, as it is heavier than air. LPG vapors can run for long distances along the ground and can collect in drains or basements cylinders can explode if involved in a fire. The health impact this dangerous gas can cause cold burns to the skin and it can act as an asphyxiate at high concentrations. Leak cause a negative effect to the health such that the hydrocarbons and other chemicals of the LPG causes very long sleep. It also causes irritated respiratory tract, nose and eyes. fIntroductionGet price
