The SPX Electric high quality AC Contactor is an electrical device that uses electromagnetic force to control the closing and opening of contacts, and is used to connect or disconnect the main circuit of an electric motor or load. It is widely used in automatic control circuits, with the main
control object being the electric motor. It can also be used to control other electrical loads, such as electric heaters, lighting, welding machines, capacitor banks, etc. Its working principle is mainly based on the combination of electromagnetic induction and mechanical transmission. SPX Electric AC Contactor has been the first choice for industrial and civil fields because it has superior performance rather than the other traditional AC Contactor.
Start and stop control: Start and stop the operation of the motor or equipment by controlling the closing and opening of the contacts.
Overload protection: Equipped with a thermal relay protection device, it monitors the current and protects the equipment from overload damage.
Electrical isolation: Isolate the circuit when it is on to ensure the safety of maintenance personnel at work.
Remote control: Connect to the control system or control panel to achieve remote control of the start and stop of the motor or equipment.
SPX Electric factory can provide customized AC Contactor with Current 10-100A.
The electromagnetic coil design of the SPX AC contactor has been optimized to reduce energy consumption.
The electromagnetic system is designed to be silent, reducing operating noise.
Reduce the risk of accidental electric shock and ensure operational safety.
Enhance electrical safety in compliance with national standards.
It is suitable for frequent operation and remote control of strong current circuits, and has a low-voltage release protection function
When choosing an AC contactor, the parameters should be matched according to the load characteristics: the rated voltage of the main contact must not be less than the line voltage, and the rated current must meet the load requirements (for resistive loads, the rated value should be used; for motor loads, it should be slightly larger). The voltage of the attracting coil is selected based on the complexity of the control circuit (380V/220V for simple circuits and 36V/110V for complex circuits), and it is necessary to ensure that the number and type of contacts meet the control requirements. Working environment factors (such as temperature and humidity) and product reliability (avoiding inferior materials) also need to be taken into consideration.
