” interference electricity ” Appear the intersection of voltage and drop or several seconds such as short interrption such as voltage greatly because of meaning the trouble that the electric wire netting is because struck by lightning or shorts out,etc., so the phenomenon that can’t work normally with the electrical equipment. Because the work of the low tension motor adopt more starting control equipments such as AC contactor, soft starter, frequency conversion speed controller,etc., in the interference electricity, the AC contactor will be released, soft starter and frequency conversion speed controller will shut down, in industrial production, often reason ” interference electricity ” Cause a lot of important undervoltage electrical machineries to shut down, and the closed-down of key aircrew will cause the big aircrew, even the whole production device is interlocked and parked, cause the serial production process forcing to cut off, production device to be forced emergency stop, cause the huge economic loss to enterprise, will also cause malignant accidents such as the fire, exploding,etc. sometimes.
MRR is in ” interference electricity ” After finishing, only ” interference electricity ” Duration exceed set for ” The interference electricity ” Allow the intersection of time and Tm ‘ 0.1- 25s) ,Already according to time Td that has set for ‘ 0- 25s) Restart the quilt ” Shake ” The electrical machinery stopped, such as ” interference electricity ” Duration exceed set for ” The interference electricity ” Allow time Tm, then MRR occludes and restarts the function. , like there are many electrical machineries, only need MRR to set for the starting time again of different one, can realize batch is restarted at the scene.
MRR that Canadian VPT Company developed has adopted unique technology, has guaranteed to presume the power down of the parameter is not lost, have high, small and installing convenient, such advantages as the interstar connection is simple reliability, but direct mount is in the scene undervoltage switch cabinet, and MRR has no part which users safeguarded, such as battery,etc..

Item Model:
It is the AC contactor of 220V AC 50/60Hz that MRR-220 is suitable for the working voltage of the coil
It is the AC contactor of 380V AC 50/60Hz that MRR-380 is suitable for the working voltage of the coil
