Earth Leakage Relay Wiring:
This diagram shows how to make Earth Leakage Relay Wiring. In this circuit, we use 3 phase energy meter, an FP MCCB ( Four Pole Molded Case Circuit Breaker ), a CT coil, and a 3-phase motor, and an ELR ( Earth Leageake Relay ). This circuit is very simple and easy to make. If you want to know more about this circuit please check our youtube video below the post.

Components used to make the Earth Leakage Relay Wiring:
The Meter Which is used for Measuring the Power of 3 Phase supply is known as the 3-phase energy meter. A 3-phase Energy meter is a Three-phase 4-wire direct Connected meter that is Used to estimate the electricity on the Three-phase power supply, mostly for residential & commercial use. A Three-phase meter helps consumers & utilities in revenue protection. It Provides Data Storage and Communication Facilities as well. The 3-phase meter is Constructed by Connecting the two single-phase meters through the shaft.
02. FP MCCB:
The MCCB consists of a bimetallic sheet that expands and contracts when the temperature of the MCCB changes. Due to overload, the bimetallic strip will start to bend and eventually, it will trip if more current flows in the circuit than the predetermined current. The trip mechanism opens the breaker. MCCB stands for Molded Case Circuit Breaker. It is another type of electrical protection device that is used when the load current exceeds the limit of a miniature circuit breaker. The MCCB provides Protection against Overload, and Short Circuit Faults and is also used for Switching the Circuits.
A current transformer is a device used to measure alternating currents. The transformer used with the ammeter for high-quality AC current measurement is called a current transformer abbreviated as CT. Current transformers are mainly used to measure high currents. We know that high power lines carry a lot of currents. In this case, an ordinary ammeter or multimeter cannot measure this current. Current transformers are used in Acorn.
ELCB complete earth leakage circuit breaker works on earth leakage production. Usually, the ELCB circuit breaker has two cables Phase and Neutral if any load is directly connected to the earth without taking neutral from ELCB then the circuit breaker will trip automatically. Earth leakage circuit breakers are used in applications to prevent electric shock and electrical fire caused by a short circuit or overload in the control panel by automatically closing when leakage is detected.
A Three-Phase electric motor uses a 3-Phase Power Supply to Convert Electric Energy into Mechanical Energy. It contains four Wires (Three hot Wires and one Neutral Wire) and Uses 3 Alternating Currents of the Same Frequency. Since it Generates a Rotating Magnetic Field, it does not need a Capacitor for the Startup. Some Three-Phase Motors are Reversible, Which Means they can serve as Generators by Turning Mechanical Energy into Electrical Energy.
