Monitoring/protection three-phase relay for overvoltage, undervoltage control

GKM-11 - Single-phase overvoltage and undervoltage relay, TENSE

Product description

The GKM-11 relay is used to protect sensitive equipment against overvoltage and undervoltage in single-phase distribution systems. If the set upper or lower voltage limit is exceeded, the relay opens the output contact and disconnects the load, preventing damage to the equipment.
