The main structure and working principle of the second thermal overload relay
The contactor is a formal direct-acting double breakpoint structure, with a cover and a body Made of arc-resistant plastic, it adopts automatic arc extinguishing, and the shaped arc extinguishing blade is placed in the body to form a closed arc extinguishing chamber with good arc extinguishing and the arcing distance is zero. The contacts are made of silver-based alloy materials that are resistant to welding and electrical wear. They have good electrical conductivity, long life, and no pollution to the environment. The iron core adopts a square structure and is small in size. There are two ways of wiring the coil
for users to choose. One has two terminals at the same end of the product, the other has two terminals at both ends of the product. The wiring is flexible and convenient
The base is made of fiberglass reinforced plastic, which has high strength and good dielectric properties. The installation method can be screw installation or guide rail installation.
It is easy and quick to disassemble and assemble. The conductive parts are not exposed and the safety performance is good.
Three normal working conditions and installation conditions
The altitude of the installation site does not exceed
The ambient air temperature does not exceed + degrees, and the average temperature value within it does not exceed + degrees. The lower limit of the surrounding air temperature The relative temperature of the air at the installation site shall not exceed +°C at the highest temperature. Higher relative temperatures may be allowed at lower temperatures, such as
°C, which may occur occasionally due to temperature changes. Special measures should be taken for condensation.
The pollution level of the installation site is level
The contactor is allowed to be installed vertically or horizontally. When installed vertically, the inclination with the vertical should not be greater than plus or minus, see the picture
Four correct installation wiring
Note that the terminal mark indicates that the main circuit is the incoming end and the outgoing end. The incoming terminal of the normally open auxiliary contact is
The outgoing terminal of the normally open auxiliary contact is
The incoming terminal of the normally closed auxiliary contact is
The outgoing terminal of the normally closed auxiliary contact is the coil terminal. and
Contactors and thermal overload relays
Contactors and thermal overload relays are suitable for construction and industrial fields, such as motor control heating and ventilation air conditioning water pumps lifting equipment lighting and correcting power factor, etc.
Thermal overload relay specifications include contactor groups up to and including micro contactors, construction contactors, snap contactors for household and industrial use, thermal overload relays and electronic relays
as well as a complete range of accessories to ensure Choose flexibility and meet customer needs.
With the same design from contactor to motor load and a wide range of DC/AC applications, only a few components are needed to meet your needs. It combines the latest electronic design and component distribution features and incorporates the latest developments in safety materials and electronics.
The new series of contactors offers a completely new concept. The combination of short-circuit protection with/without fuses and electronic overload relays provides the basis for the development of a new generation of systems. Our mission is to provide designers, engineers and end users with the best system solutions.
