That could shutdown the entire control circuit to avoid problems. 600VAC PVT - Din mtg. Three phase motor Conveyors Blowers System integrators Elevators Three phase voltage relays are used in applications typically involving three phase motors. The purpose of the three phase voltage relays is to avoid damage to a motor because of a line voltage problem. If any of these conditions occur, the three phase relays can be wired into the control circuit to disconnect the motor from the line voltage via a starter or contactor or turn on an alarm.
Some units are plug-in, some surface mounted and some are din rail mounted.
600VAC PVT - Din mtg. These products can go from 30 millivolts up to 100volts. Operation is usually that when the voltage goes lower than the set point, the relay output contacts will de-energize. If the voltage is higher than the set point the output relay is energized. Low or stopped motor rotation Press machines Rotating equipment Conveyors R-K manufacturers two types of speed switches.
