Feature: \n 1. Widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, electric control boxes, power distribution cabinets, cranes, etc.\n2. It is an indispensable protection product for the normal working voltage of the maintenance equipment in the operation of industrial equipment.\n3. Installation method: The base of the protector adopts the rail type, and there are two M4 screw holes in the structure, which can be directly installed separately or installed on the HT35 rail.\n4. Overvoltage protection: It means that the voltage of the protected line is higher than the set value, and the delay is 3~8S, and the recovery is 6~20VAC.\n5. Undervoltage protection: It means that the voltage of the protected line is lower than the set value, the delay is 3~8S, and the recovery is 3~20VAC. \n\nSpecification: \n\nTVR2000-3 voltage phase sequence multi-function protector is also called three-phase power relay, phase sequenc:
