HANNOVER MESSE 2020,
20 - 24 April
New series of earth leakage relays designed to detect earth leakage current in an intuitive and automatic way. The multicolour display allow a continuous and immediate control of the insulation status and are able to operate, without causing nuisance tripping, even on very perturbed systems. Main features: - Continuous digital indication of leakage current - Actuating current storing - Internal clock with last 10 events storing - RS485 Modbus RTU, Measures, event archive - Selectable antifibrillation low pass filter - Selectable 3rd harmonic low pass filter - THD visualization and measuring - AC measuring up to 2500Hz
