🔰 Contactor
Contactor is one of the most important and widely used equipment in industrial electricity. A contactor is a type of electrically connecting and disconnecting device (electromagnetic switch) that is used to switch a power/control circuit. This piece is the most important component of electric steering circuits. The contactor is used in high amperes using the same function as the relay function. As a result, due to the use of high amperage, the speed of disconnecting and connecting its contacts is lower compared to the relay.
🔰 Metal relay
One of the industrial electrical tools is thermal relay (non-metal) which is used to protect electric motors against overload. These relays are made by joining two non-homogeneous metals together. Due to the current passing through bimetal, two metals are heated and their length increases. It works due to the difference between the expansion coefficient of these two metals. As a result, the current path of the contacts is opened and the circuit is cut off.
🔰 Miniature key
A miniature switch or a miniature fuse is a device that protects electrical circuits against excessive and unauthorized current. If the current exceeds the limit, the power will be cut off. Today, in the electrical wiring systems of a building, various devices are used for greater safety, and one of these devices is a miniature switch that protects electrical circuits against unauthorized current. Miniature switches are non-adjustable and can be operated magnetically or thermally.
🔰 Chassis
Another equipment used in industrial electricity is the chassis, which is used to transmit the connecting and disconnecting command to relays and contactors. The body of the chassis is usually made of metal or plastic or bakelite. Based on the diameter, appearance, color and type of transmission, the chassis can be divided into different categories. In fact, the chassis is a key that is activated by fingers and by pressing. The volume of the chassis is smaller than other keys and their weight is lighter.
🔰 The thermal key
Other industrial electrical equipment can be called the thermal switch, which has high security. A thermal switch is a type of circuit breaker that is used as a protection against overload and short circuit. The thermal switch can cut off the magnetic current and can cut or connect the motor circuit during operation. Thermal switches disconnect and connect the power circuit and can be installed together with peripheral equipment for use in the control circuit. The thermal switch has two main protections including magnetic protection and thermal protection.
🔰 Rail terminal
The rail terminal is one of the most used equipment in the field of industrial electricity, which enables the connection and connection of other equipment to each other. To choose the correct terminal, you should consider the following: 1- The brand of the rail terminal manufacturer 2- The type of the terminal 3- The maximum current that can be tolerated 4- The size of the wire that can be connected 5- The number of floors 6. Color.
