Elcb circuit diagram manual

The ELCB detects fault currents from live to the earth (ground) wire within the installation it protects. A voltage-sensing ELCB does not sense fault currents from live to any other earthed . The ELCB notices fault currents of human or animal to the earth wire in the connection it guards. With this function, the ELCB can protect the circuit against overload and short circuit or can be used for the unfrequent switchover of.

Please peruse this instruction manual before using.

Before setting, turn off the upper circuit breaker, or turn off the circuit breaker to be set or trip the breaker, then make sure of no current conducting.

A simple ELCB circuit is discussed here. As shown in the diagram , a simple bootstrapped amplifier network forms the main sensing stage of the unit. Once widely use more recent installations instead . Switching, control, visualization.

Electronic motor starters and drives. Motor-protective circuit -breakers. Export to World Markets and North America. All the circuits controlled by microcontroller, PIC 16F877A so that the operation of this project operates with directive and fluent.
