Home ProductMulti-Function 3 Phase Voltage Relay
The Phase Sequence Failure Voltage Relay is a phase sequence comparator consisting of an op-amp that compares phase sequence voltage amplitude, frequency high and low, and phase. Our relay is of good quality, with low error and low repeatability errors. It is designed with snap type, easy to install. Also, it has a high rail base for more safety and durability. If you are looking for the Phase Sequence Failure Voltage Relay, we promise that our product will not let you down since it has incomparable advantages.
Features
Our Phase Sequence Failure Voltage Relay is superior in quality and moderates in price so that is saleable in the market. It is quite easy to use as it automatically cuts off the circuit when the phase sequence does not match. It is equipped with a user-friendly control panel, and the data sheet displays the status of the device in time, which is very intuitive. Our products are manufactured according to industry standards, with guaranteed quality and long service life.
