Earth Leakage Relay Connection With CBCT | Full Wiring & Working Explained In this video, you will learn the complete process of **Earth Leakage Relay (ELR) connection with CBCT Protect people and equipment from hidden ground faults with Minilec’s S2 ELR1 Earth Leakage Relay and CBCT system. Earth leakage relays are used in combination with Core balance current transformers (CBCT) or Zero phase current transformer (ZCT). Earth leakage relay is a sensing device that senses the earth leakage current and sends signals to the circuit breaker to trip the circuit or disconnect the main power supply. Accurate leakage detection, adjustable trip settings, and reliable protection for industrial and commercial three-phase electrical systems. fs3004a , Auxilliary Transformer 80va Pri-500 525, Part no. fs3004b , Ic And Tg Cable Box Complete Fs3 without, Part No. CBCT (Core Balanced Current Transformer) is an accessory to be used with 7UG0842-1AD21 (Earth Leakage relay). Selec ELCTR35-1-300mA: Earth Leakage Relay with Inbuilt CBCT (300mA Fixed). When its output exceeds the present limit (leakage current limits can be set), the relay contacts operate. The CBCT / ZCT mounted externally and load current carrying cable is passed through the CBCT / ZCT. The Serial No. Working in conjunction with a CBCT, it will trip the circuit breaker when earth leakage goes above the programmed threshold. We offer reliable Earth Leakage Relays at competitive prices. This relay, in turn, activates a shunt coil to disconnect the faulty circuit, preventing electrical hazards. The difference between them lies at the magnitude of current they sense and usage. High Precision: Microcontroller-based design ensures accurate sensing and trip timing.
