ManHua 380VAC 3 Phase Protection Relay XJ11 Phase Failure Relay For Sealed Voltage Unbalance Failure Device Relay

Application and Feature:

1.CCX1 Overvoltage / Under voltage / Phase failure / Phase sequence Protection Relay (hereinafter Protection Relay), connected with the switching electrical device(like AC contactor etc.) as the protective circuit to do efficient protection for the breakdown which probably occurred over voltage,under voltage,phase failure,phase sequence in the inevasible 3 phase AC and transmission equipment( for example water pump,draught fan. Conveyer bait, air compressor, 2.Protection Relay are widely used in the low voltage power distribution system of using 3 phase 50HZ  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 human safety under the conditions as below: when the phase sequence of Protection Relay is 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 its main parts. Its feature are reliable operation, accurate failure indication, strong anti-interference, small volume, simple installation and use , furthermore it cannot be influenced by the big or small power of been protected equipment.

Work and installation conditions:

1.Ambient temperature: ≤+40℃ and ≥-5℃

2.The heights of installation place is not over 2000m

3.Air condition:a. Humidity: when the temperature is at +40℃, the air relative humidity is not exceed 50%. The higher relative humidity is acceptable the lower temperature, for example the humidity can reach up to 90% when 20℃, please adopt the special method for the condensation due to the temperature fluctuation. b.Pollution Grade: Pollution grade 3 of Protection Relay (electric conduction pollution or to the condensation make the dry un-electric conduction to be polluted to become electric conduction).

4.Installation:a. Installation: 1)screw mounting   2)35mm standard DIN rail mounting. b. For safe operation, Protection Relay should be installed uprightly relative to the ground.

Technical date:

Notice:

Terminal L1,L2,L3 of protection relay connect with 3-phase live wire, terminal Ta,Tb,Tc are the output contact of protection relay, terminal Tb,Tc are normal closed, terminal Ta,Tc are normal open. When power on and after that, terminal Ta,Tc convert to normal open, terminal Ta,Tc convert to normal closed. When the protection relay does the protective operation ,terminal Ta,Tc convert to normal open again.
