MCB and ELCB
MCB and ELCB
MCB (miniature circuit breaker) is electromechanical protector which protects from low voltage electric network instead of fuse. It protects the wiring from severe damage caused due to very high or low voltage. Which is to be carried a current which is too high for the diameter of the wires.
ELCB (earth leakage circuit breaker) is a device which breaks the power supply that flows through the earth line wires. Imperial world Trade is the leading MCB and ELCB manufacturer in India. It is supplier of MCB and ELCB as well as exporter of MCB and ELCB which exports these products in USA, UK, UAE and Nigeria.
Usage of MCB and ELCB
MCB's main function is to break the consistency of electric flow if any error detected. Rearranging MCB devices are very simple thus it gives better protection at reasonable cost. If the current flow exceeds the maximum acceptable limit the MCB works as switch which will turn off in such condition. It protects from overloading, short circuit and switching.
ELCB's main function is to break the circuit in case of unsafe voltage is detected. This is to protect the humans and nature from injuries caused by the electric shocks caused by earth leakages. This circuit interrupter disconnects the supply of power in case of unsafe conditions. We can say ELCB is the brain and grounding is backbone for shock protection.
We are MCB and ELCB manufacturers since long ago. We are the MCB and ELCB suppliers and cover much bigger market of India. We as MCB and ELCB exporters supplies in leading countries like USA, UK, UAE and Nigeria. We have large customer base who are satisfied with our service and quality of product.
Features of MCB and ELCB
Listed are the features of MCB
- Adjustment of trip characteristics is not normal.
- Thermal or thermal - magnetic operations.
- Rated current not more than 100 A.
Listed are the features of ELCB
- The phase, earth wire and neutral are connected together by ELCB.
- Its working is dependable on the current leakage.
Importance of MCB and ELCB
Before the invention of MCB, wired fuses used to get protection from short circuit. In that, there is thin wire used in the circuits. If a fault occurs, as the current flows higher and triggers the max limit, the fuse wire starts getting hotter and after a point gets so hot that it starts melting and breaks the flow of current in circuit so as to protect it.
Problem with these fuses was that some of them are designed faster than the others. But this whole process of fuses to react takes a much longer time as compared to today's used MCB's. These MCB are work within fraction of time.
If we talk about ELCB, it is used to protect from insulation failure. If the current leaks from installation of electric circuit, there could be insulation failure, which must be detected and protected effectively, otherwise there will be higher risk of shock if anyone touches installation. This will be effectively done by ELCB's.
