The new EMD-SL-PH-690 monitoring relay from Phoenix Contact monitors the electrical parameters for phase sequence and failure as well as undervoltages in applications up to ambient temperatures of 70°C.
It can be used in three-phase networks of 690 V AC thanks to the high monitoring and measuring range. With an overall width of just 22.5 mm, the monitoring relay comes in narrow, space-saving housing. The relay is UL listed and can be used worldwide, especially in the USA and Canada. The monitoring relay was developed because prompt detection of deviations in system parameters is essential in areas with high ambient temperatures in order to ensure the required system efficiency and reliability.
