Thermal relay what it is and how it works
Posted: Thu Dec 12, 2024 10:24 am
Thinking about signing up for solar energy? If so, it's worth getting familiar with some concepts. Without a doubt, the thermal relay is one of the essential ones.
What is a thermal relay?
Basically, thermal relays are devices that act as an automatic switch that trips to protect an electrical installation against network overloads. In other words, it is an element that prevents a motor or installation from being damaged by a sudden rise in voltage or overheating.
Given their important protective function, the relays are manufactured sale leads zimbabwe email address under strict ISO standards . This ensures that they meet all the essential characteristics of this type of element, including:
That they can be used with both alternating current and direct current.
Automatic or manual restart of the ignition, depending on the nature of the installation you are working on. The manual option is essential for sophisticated equipment that requires technical ignition. On the other hand, automatic restart is common in private installations, such as photovoltaic panels.
The metal plate made of a resistant material. This is the basic part of any relay, as we will see when discussing its operation. Normally, it is an alloy of nickel, brass and iron.
Existence of different types of relays, adapted to the equipment to which they will be connected.
Before we go any further, we want to reassure you. Despite what it may seem, the devices we are talking about are very simple. They can be operated even by someone with zero knowledge of electricity.
What is a thermal relay used for?
Initially, thermal relays are usually associated with industries, specifically with the electric motors used by these types of companies. It is logical to understand that these are large-scale installations that require a large investment. Therefore, it is essential to have some protective measure that prevents equipment breakdown or an interruption in the energy supply.
However, the device we are referring to is a much more widespread element. In fact, they are found in all types of electrical system assemblies. Consider that it is a small and very affordable device. But, above all, its presence prevents much more serious damage and harm.
Finally, it is worth remembering that a thermal relay has other functions, in addition to the protection function that we have already explained to you:
It performs a test of the electrical system that allows detecting possible faults or problems.
Reduce power outages.
