What are the differences between circuit breaker and fuse ?
The differences between circuit breakers and fuses.
Both residential and industrial electronics circuits systems require some form of protection to
prevent catastrophic failure circuit damage or loss of life due to excessive current brought on by a short circuit overload device failureĀ or other unforeseen elements.
The two most common forms of circuit protection areĀ fuses and circuit breakers.
Fuses are made up with a filament enclosed in a glass porcelain or ceramic case. This filament
normally completes the circuit.In the Ā event of an Ā overload or short the metallic filamentĀ melts and opens the circuit.
Circuit breakers use a set of contacts toĀ complete the circuit.The switching mechanism has a metallic lever that can be actuated by a solenoid for a bimetallic plate.with magnetic circuit breakers the
short-circuit current charges theĀ solenoid attracting the metal leverĀ that trips the device.Thermal circuit breakers often found in residential use.A Ā bimetallic strip that expands when
heat is applied.Once, enough heat has been generated due to an overloadĀ the unit will trip.
