XJ3 Protection Relays For Transmission Equipment
- Product Name: Protection Relays
- Product Model: XJ3
- National Standard: GB/T 14048.5
- International Standard: IEC 60947-5-1
- Certificate: CCC CQC
- Mechanical Life: : ≥ 1 million times
- Electrical Life: ≥ 100,000 times
Overview
XJ3 series protection relays are used in the three–phase AC motor control circuits for phase loss protection and in the irreversible transmission equipment for phase sequence protection.
The XJ3 is connected to the power control circuit according to the method shown in the wiring diagram for protection, and can work when the fuse of any phase in the three–phase circuit is burnt or the circuit opens to cut off KM main circuit power; XJ3–2 relay only works for protection of the phase loss when the motor starts rather than during the operation of motor, thereby realizing the purpose of motor protection.

Product Description
1. XJ3 Protection Relays Application:
XJ3 protection relays are for equipment (such as water pumps, fans, air compressors, elevator motors, small and medium–sized distribution panels) with irreversible three–phase, after the phase sequence is identified, the XJ3 can also work reliably and identify the phase sequence when the actual phase sequence is different from the original identified phase sequence due to the repair or changes of the power supply line to cut off the power supply of KM main circuit for equipment protection.
2. XJ3 Protection Relays Working and Installation Conditions
2.1 Protection relays working environment: the altitude does not exceed 2000 meters; the ambient temperature is not higher than +40°C and not below –5°C; the voltage variation range of the rated control power supply is 85%–110% of the rated voltage; Installed in places where there is no medium without harsh vibration or explosive hazard or the medium does not contain gas or conductive dust that causes metal corrosion or damage to the insulation free from the rain or snow erosion.
2.2 Protection relays vertical or horizontal installation.
3. XJ3 Protection Relays Technical Features:
3.1 Rated insulation voltage Ui: AC380V
3.2 Rated impulse withstand voltage UimP: AC1.5kV
3.3 Rated operating voltage Ue / Rated operating current Ie under the usage category:
AC–15 Ue/Ie: AC380V/0.95A;
AC240V / 1.5A; AC120V / 3A
3.4 Protection relays resistive current Ith: 5A
3.5 Rated operating voltage: AC380V three–phase
3.6 Protection relays pollution level: 3
3.7 Three–phase imbalance: 7%~10%;
3.8 Protection relays mechanical life: ≥1 million times
3.9 Protection relays electrical life: ≥100,000 times
3.10 Cooperation with the short circuit protective device (SCPD): The RT16–00, 6A fuse with “1” type basic protection is recommended as SCPD; that is, the relay shall not cause danger to the persons or equipment in case of short circuit, and it is not allowed to work continuously before the repair or replacement of parts. If the fuse protective device of the different model is selected, the original cooperation may fail.
