UKC1-400 AC Contactor

Product Features

1. Universal type:

It is generally used in household appliances with a rated operating current less than 10A; it has the characteristics of reasonable structure and easy operation.

2. Thermal relay type:

It is generally used in electrical equipment with a rated operating current greater than 10A, and is mainly used to control the overload protection of electric heating appliances and motor speed control devices.

Its structure is simple and the price is low; the disadvantage is that when the grid voltage is lower than 10% of the rated voltage, it cannot operate reliably; in addition, because the thermal relay is a normally open contact, it is easy to burn out the coil or cause a fire when the load is short-circuited. .

3. Electronic type:

It is generally suitable for motor starting control and lighting circuits in low-voltage lines. It has the advantages of small size and light weight; at the same time, the microprocessor is used as the controller for control processing, which significantly improves the reliability of the product.
