1. Introduction to "circuit breaker" 1.1 What is a "circuit breaker" A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break ...
different loads 1. Contactors are used for load types that have high voltage, high current, or both. Generally speaking, it is used for equipment passing more than 15 amps or more than 3kW load. For lower quantities, normal rela...
The definition of relay: a relay is an automatic control system component that will produce a jumping change in cardiac output when the output (electricity, magnetism, sound, light, heat) reaches a certain value. First, the p...
The function of the automotive relay is to control the magnitude and on-off of the current. The following is a detailed introduction about automotive relays: 1. Automobile relay is an automatic control device whose output will c...
one, The working principle and characteristics of the relay Relay is an electronic control device, it has a control system (also known as input circuit) and a controlled system (also known as output circui...
The types of relays include electromagnetic relays, voltage relays, time relays, pressure relays, thermal relays, overvoltage relays, static voltage relays, hot wire relays, solid state relays, and thermal reed relays. Types...
Safety relays are relatively common electrical appliances in industrial circuits. Many people are unaware of safety relay options. How to choose a high-quality safety relay is a problem for many people. So what should be the basis for choosing ...
Working principle of thermal overload relay: Thermal overload relay is a protective electrical component that uses the thermal effect of current to drive the action mechanism, thereby cutting off the control circuit, and then cutting off th...
