Detailed Description
 


CJX1 Overvoltage/undervoltage/phase failure/phase sequence protection relay(hereafter called protection relay) connected with

Application and feature

1) CJX1 Overvoltage/undervoltage/phae failure/phase sequence protection relay(hereafter called protection relay) connected with the switching electrical device(like AC contactor etc) as the protective circuit to do efficient protection for the breakerdown which propably occurred over voltage, under voltage, phase failure, phase sequence in the irreversible 3 phae AC electricmotor and transmission equipment (for example water pump, draughtfan, conveyer belt, air compressor, feeder line)

2)Protection relay are widely used in the low voltage power distribution system of using 3 phase 50HZ, AC380V in the industry, agriculture and service.

3)Protection relay can disconnect the power supply of the main circuit to reaching the purpose of protecting the equipment and humen safety under the conditions as below: when the phase sequence of protection relay is confirmed. Wrong connected with the pre-confirmed phase sequence due to change or maintain. occurred phase failure in the supply circuit, occurred over voltage or under voltage in the supply power grid.

4)Protection relay adopts the advanced technique of voltage test and excellent IC as its main parts. Its feature are reliable operation, occurate failure indication. strong anti-interference small volume, simple installation and use. further more it can not be influenced by the big or small power of been protected equipment.

Main technical data

1)Power voltage: AC50HZ, 3phase 300V~400V

2)Overvoltage protection: 380V~460V can be adjusted, delay time 0.5s~5s can be adjusted

3)Under voltage protection: 300V~380V can be adjusted,delay time 1s~10s can be adjusted

4)Phase failure and phase sequence active time≤0.2S

5)Mechanical time: 1000,000times

6)Electrical time: 100,000times

7)Contact capacity:AC220V 5A(Resistance)

8)Power consumption:≤2W
