Overcurrent is when an excessive amount of current than the intended amount passes through a conductor or any electric network are frequent events in compact systems with sophisticated electrical wiring. You may have witnessed severe damages of the equipment or fire hazards at your households and workplaces which are the possible after effects of such events. For such extremely sensitive micro components in today’s sensitive electronics you might need an add on to your network such as Fuses, circuit breakers, current limiters, Surge protection devices, etc.
Plugging in too many devices causing circuit overload¸ short circuiting, grounding earthing System fault pave way for electric faults into your systems.
Understand how Protection devices help on that account:
Circuit breakers or fuses – Properly rated breakers or fuses installed at your main service panel can serve the purpose of handling the overcurrent or limiting the current to the required value prescribed by the manufacturer further protects your electric/ electronic devices.
Surge protection devices or transient surge suppressors – Speaking of the above said typical circuit breakers and fuses are not capable of detecting huge and sudden voltage spikes called the surges, instead the surges will pass through and blow off the appliances. Hence, surge absorbers are the key component that are an excellent investment capable of shielding life and property from catastrophic effect due to rapid hike in nominal line voltage which are called surges. Surge absorbers implanted in between the device and the main circuit board are critically important passive circuits that protect vulnerable devices by paving way for fault currents safely to the ground.
There are basically different types of SPDs available as per the application and also based on the parameters such as maximum continuous operating voltage and nominal discharge current ratings while choosing the appropriate SPD. One must particularly note that inappropriate choice of SPD can be worthless.
