一、Characteristics of protection
1.Phase loss protection: It means that any phase occurs phase loss when the protected
circuit is in running or stopping status. In this case, the red indicator light will be lighted and be priority.
2.Phase opposite protection: It is a safeguard acting immediately, which protects L1, L2,
and L3 three phase against wrong connection sequence. In this case, the yellow indicator
light will be lighted.
3. Voltage imbalance protection: While a protection of voltage imbalance rate > 8%, the

imbalance of three phase voltage will affect the safe running of the equipment. In this case
that there is a phase losing, the red indicator light will be lighted and be priority.
4.Delay protection：When the fault happens, the monitor will delay 1~2 seconds to act and
release.
二、Characteristics of performance
1.The protection functions of relay don’t be affected by current intensity of circuit or load,
impulse current, imbalance current and load characteristic. The relay could long term work
under full capability and full climate. Power consumption is lower than 2W.
2. There is no requirement for connecting method when it is used in protection of motor.
3. This product measures up GB/T 14048.1-2000、GB14048.5-2001 eqv IEC60947-1:1999.
4. The EMC of the product measures up the limits and methods of measurement of radio

disturbance characteristics of GB4343-1995.
三、 Characteristics of working
1.If the connection of L1, L2 and L3 phases are right, the green light of the relay
illuminates and the relay closes. If they are wrong, the yellow light of the relay illuminates.
Exchanging any two of them, the relay will accept the phase sequence and begin to work
normally. In this case that there occurs yellow light illuminated and relay unclosed after the
protected equipment works normally, it should be a wrong connection of external circuit.
The relay has a function of protection against wrong connection.
2.While any of these L1, L2 and L3 phases is Na phase, the red light is lighted with the
unlighted green light and the released relay. While the voltage come back to normal, it will
recover immediately with lighted green light and closed relay.
3. L1, L2 and L3 connect with three phase AC. NO, COM are normally open contact point

and NC, COM are normally closed contact point. Use lead to connect terminal directly.
