Home ProductMulti-Function 3 Phase Voltage Relay
The Phase Failure Protection Voltage Relay is mainly used for AC 50/60Hz, rated voltage below 460V for various fault detection. It is capable of providing relay protection for over-voltage, under-voltage, phase loss, phase breakage, phase sequence, three-phase voltage unbalance, etc. for three-phase input power. Our products are beautifully light outside, small in size and occupy little space. The Phase Failure Protection Voltage Relay is available in a wide range of voltage ratings.
Features
Compared with similar products in the market, we believe that our Phase Failure Protection Voltage Relay is of better quality and lower price. It features a standard modular construction and din rail mounting. The product uses LEDs to display voltage values, fault status, and parameters. Over-voltage and under-voltage values are adjustable, and the operation time is adjustable for more flexible use. The voltage unbalance rate and operation time are also adjustable, making it easy and convenient to use.
