JVR-384 overvoltage and low voltage protectors are mainly used for AC 50/60Hz, rated voltage less than 460V, industrial three-phase 220V, 380V, 440V, 460V, and other voltage levels of fault detection. Relay protection against high and low voltage of the three-phase input power supply.
Function:
1. Widely used in air compressor, electric motor, distribution box, water pump, oil pump, central air conditioning unit, electric control box, distribution cabinet, crane, etc.
2. Central air conditioning compressor protection, various elevator power monitoring, pump and oil pump defects, reverse phase protection, etc.
3. An indispensable protection product for the normal operating voltage of service equipment in the operation of industrial equipment.
4. Installation method: The base of the protector is rail type, the structure has two screw holes, can be installed independently or installed on HT35 rails.
5. Indicator: Normally indicated by 3 indicators of overvoltage, low voltage.
6. Over Voltage Protection: The voltage of the protected line is higher than the set value, the delay is 3-8S, and the recovery is 6-20VAC.
7. Low Voltage Protection: The voltage of the protected line is lower than the set value and the delay is 3-8S, and the recovery is 3-20VAC.
8. This product complies with GB14085.5-2001 eqv IEC60947-1:1999 standards.
