In the power world, contactors are a critical device that play an important role in switching, controlling and protecting circuits. As an electrical component, the main function of a contactor is to connect or interrupt the path of current in a circuit. The application of contactors almost lays the foundation for electrical technology. Therefore, a […]

Circuit breakers play a crucial role in electrical operations, serving to distribute electrical power, initiate asynchronous motors infrequently, and protect power lines and motors. They can be seen as a combination of fuse-style switches and thermal overload relays, forming a protective mechanism. In the event of severe overload, short circuit, or under voltage faults, circuit

A residual current device (RCD) is a common electrical device used to detect whether there is a leakage in a circuit and cut off the circuit immediately when a leakage is found. In domestic and commercial environments, the role of earth leakage protectors is crucial because it can prevent safety accidents such as electric shock

Today we will talk 10 differences between a contactor and relay. Contactors and relays are two common electrical control devices. Their differences are mainly reflected in appearance, structure, function, application scenarios, etc., as follows: Table of Contents 1. Appearance difference between a contactor and relay Contactors are usually larger than relays, and have a structure

Contents Overview Thermocouples are divided into K type, N type, E type, J type, T type, S type, and B type according to their different materials, so the measured temperature also has certain differences, and their advantages and disadvantages are also different. 1. K thermocouple A K type thermocouple is made of nickel chromium-nickel silicon
