KOMPAS.com – Miniature circuit breakers or MCBs are one of the most important electrical equipment in a home to avoid short circuits and fires.However, simply having and installing this tool is not enough.
You can’t just buy and install MCB.Either way, the device you’re using is counterfeit and dangerous to yourself and your family.
There are a few things you must consider when buying an MCB to avoid being fooled by counterfeit products.First, consider the four components commonly found in MCBs, namely the arc chute, bimetal, solenoid, and switch lever.

Bimetals can detect overcurrent.A continuously increasing thermal load will cause the component to expand, causing the current to automatically shut down.
At the same time, the electromagnetic coil will protect the grid from short circuits.The function of the arc chute is to extinguish the fire, ie if there is a moving contact or if the MCB lever is manually opened.
“However, it is really difficult to see the components in the MCB, because it is related to the interior. The solution is to ask for an official certificate, because the original electrical equipment always comes with a certificate,” said PT Schneider Electric Riyanto Mashan, Indonesian National President, Kompas.com .
Riyanto continued that the public must also remain vigilant if they find MCB prices too low.According to him, MCB devices may be counterfeit or use unsafe components.
“Actually, the easiest way is to choose a device that complies with the national standard (SNI). It’s definitely guaranteed to be safe,” Riyanto added.
PT Schneider Electric Indonesia ELCB terminal will accompany MCB.Unlike MCBs that protect against short circuits, ELCBs or Earth Leakage Circuit Breakers protect the human body from “leakage” or current leakage.Quite easily, the ELCB will provide safety so that humans cannot be electrocuted.
Riyanto suggested that even if MCBs are used, it is highly desirable to install earth leakage circuit breakers (ELCBs) as an additional safety device.The tool will cut off the network immediately, especially if the current leakage exceeds the safe threshold of 30 mA.
“If a human is electrocuted (within safe limits), the current won’t cause death. The side effect is just shortness of breath,” Riyanto said.
ELCB sensitivity can help MCBs prevent house fires.This network circuit breaker device also insures you and your family from the risk of current leakage beyond safe limits.
Even safer, get in the habit of asking an electrician in detail during network installation.If you’re familiar with appliances in your home, you can repair them right away if they break down.
“For older houses, don’t forget to check and replace the electrical equipment regularly so that all tools are always in top condition,” Riyanto adds.
