EL731-20-10 protection relay is a type of two-stage protection device used in various electrical systems, including industrial and commercial buildings, substations, power generating units and more. It is designed to protect against electrical overloads, short circuits and other faults. This type of protection relay is also commonly used in low voltage AC and DC applications. The working principle of EL731-20-10 protection relay is based on the principle of an electromechanical relay. It contains two sets of contacts – one set of contacts that are connected to the load and another set of contacts that are connected to the power supply. These contacts operate in a closed circuit to form an electromagnetic shielding which prevents current and voltage fluctuations from reaching the load.When the load experiences an overload, a current will flow through the contact that is connected to the load. This current will cause the armature of the protection relay to move, closing the contact that is connected to the power supply and opening the contact that is connected to the load. This action will prevent further voltage or current fluctuations from reaching the load.The EL731-20-10 protection relay has various applications and can be used in electrical systems such as: ● Residential and commercial applications, where it can provide protection from overloads, short circuits, and other electrical faults. ● Industrial applications, where it can help prevent damage to expensive machinery and equipment. ● Substation applications, where it can help ensure that the correct level of protection is present in the system. ● Power-generating applications, where it can ensure that the voltage and current supplied to the load are within the range of acceptable values. This type of protection relay is also commonly used in low voltage AC and DC applications.The EL731-20-10 protection relay is a robust and reliable device which can be used to provide a high level of protection for various electrical systems. It can be easily installed and offers flexibility in terms of its switching capabilities. This type of protection relay is also easy to maintain, and can be used in a wide range of applications where protection from overloads, short circuits, and other electrical faults are required.
