Characteristics of protection
1Phase 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.
2Phase 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 protectionWhen the fault happens, the monitor will delay 1~2 seconds to act and release.
Characteristics of performance
1.The protection functions of relay dont 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.
2There is no requirement for connecting method when it is used in protection of motor.
3This product measures up GB/T 14048.1-2000ã?�GB14048.5-2001 eqv IEC60947-1:1999.
4The EMC of the product measures up the limits and methods of measurement of radio disturbance characteristics of GB4343-1995.
