Nowadays, the digital world is part of society’s everyday life. May it be entertainment, business, academic or professional applications, an electronic device would most likely be needed. It is incredible how these devices can connect everyone wherever in the world, especially with today’s crisis, forcing businesses such as Sensata Technologies, , to change their strategies by incorporating technological changes to remain relevant.

Several things could hinder a device from functioning, and this is the lack of an electric source. A couple of inventions have been introduced to prolong the battery life of portable devices such as cell phones, laptops, and cameras. The mighty battery pack or power bank that stores energy for on-the-go usage is the most famous. However, this energy storing device is no different from the rest as it still needs electrical outlets to restore its power and be helpful.

Electrical outlets vary among regions/countries, forming different plugs and voltage capacities like the ones presented in the image below.


​​
Unfortunately, these variations are not merely designs, and despite their deceiving aesthetic, they carry a potential danger for you and your equipment when improperly used. Using adapters can be an option to address incompatible circuits and plugs, especially when traveling for electronics with an Extra Low Voltage ranging from 0 – 1000 AC RMS voltage or 0 – 1500 DC voltage according to the International Electrotechnical Commission Standard IEC 61140:2016.

What is Circuit Breaker Protection?
The previous discussion may have pushed you back from using your devices; the good thing is, industry experts and professionals have already foreseen the potential danger of different electronic applications. One of which is the invention of Circuit Breaker Protection Devices, also known as Circuit Breaker or CPD, short for Circuit Protection Device, and just “Breaker” as per household terms. A CPD is an electronic component protecting a circuit from overvoltage, overcurrent, or overload. These terms are used interchangeably by many, but in reality, they are different and they are explained as follows below:

Overcurrent – An excessive current starts to flow in the circuit due to a short circuit overloading the circuit, or a ground fault.
Overload – An electrical load takes more current than the standard rated capacity.
Overvoltage – A condition where operating or supply voltage is higher than the standard rated capacity specified by the system’s manufacturer. Lightning strikes are classified for this excessive charge of voltage.

The Different Circuit Breaker & Protection Devices
Testing electronic components at home can sometimes be dangerous, especially when one is unaware of basic precautions. Typically, it is best to leave these to experts, but a good amount of necessary knowledge will not hurt!

All devices in the market are expected to go through strict quality control and safety standards before being marketed to the public. We have now explained and provided you with a better understanding of the difference between overcurrent, overload, and overvoltage, so let us dig deeper and get to know the different protection devices, such as the circuit breaker for each event.
