Smart earth leakage protection Electronic earth leakage residual current protection and monitoring relay (Type B) Description Electronic earth leakage current protection and monitoring relay (IEC 62020) compatible with the protection transformers of the WGC-TB series. The RGU-10B is the most complete system for monitoring and controlling electrical insulation of type-B installations (IEC 60755). Compatible with WGC-TB earth leakage transformers —— Electronic relay with relay output. —— Measures in AC, DC or mixed current, type B (IEC 60755) —— Measures the intensity of the current by connecting to an earth leakage transformer of the WGC-TB series. —— Programmable with backlit LCD display: –– Trip current (red display when tripped) –– Parameter programming –– Instantaneous leakage current –– Disconnection of external transformer —— Status signalling via 2 LEDs —— Features two independent programmable outputs (main and prealarm). —— Includes a remote-control input. —— Assembly on DIN 46277 rail (EN 50022), 3 modules. Applications Monitoring of electrical insulation in: ——single-phase or three-phase AC installations, AC installations with DC components or purely DC installations. With frequencies of up to 1 kHz. Such as, for example: ——Speed drives ——UPS (Uninterruptible Power Supply systems) ——Photovoltaic installations ——Motor control devices, etc. Technical features Monitoring Earth leakage transformer Remote control Remote test and reset possible Associated signalling element Visual or acoustic signalling devices Power supply voltage Leakage trip Prealarm Leakage current (instantaneous value) Trip current (red LCD) Parameter programming WGC-TB transformer disconnection Remote signaling Alarm Prealarm Control of the display/control element Via 2 NO/NC switched output relays Auxiliary power supply Output contacts Operating temperature Protection degree Standards Mechanical features Electrical features
