Purpose

Cj20 series AC contactors are mainly used to connect and disconnect circuits in the electrical system with AC 50 Hz, voltage up to 660 V (individual level is 1140 V) and current up to 630 a, and form electromagnetic starters with appropriate thermal relays or electronic protection devices to protect electrical appliances that may be overloaded.

*”03″ stands for 380V, general can not be written, “06″ stands for 660V, if the product structure is the same as 380V, it can not be written; “11″ watt stands for 1140V.

Scope of application

1. Ambient air temperature

A. The upper limit of ambient air temperature shall not exceed + 40;

C. The lower limit of ambient air temperature shall not be lower than – 5 (it can also be – 10 or – 25, but it shall be declared to the manufacturer when ordering)

2. Altitude

The altitude of the installation site shall not exceed 2000m.

3. Atmospheric conditions

The relative humidity of the atmosphere should not exceed 50% when the maximum temperature is + 40; there can be higher relative humidity under lower temperature, and the monthly average maximum relative humidity can be 90% when the monthly average minimum temperature is + 25 in the wettest month, and the condensation on the product surface due to temperature change should be considered.
