An alternator that supplies three phase voltage will have the windings connected so that three phases and the neutral are available to the customers installations for most markets the three phase voltage value is 400V between phases and 230V between phase and neutral.
what is MCCB
A moulded case circuit breaker MCCB is a type of electrical protection device that is used to protect the electrical circuit from excessive current which can cause overload or short circuit.
What is ELCB
An ELCB is a specialised type of latching relay that has a building's incoming mains power connected through its switching contacts so that the ELCB disconnects the power when earth leakage is detected the ELCB detects fault currents from live to the Earth ground wire within the installation it protects.
What is MCB
MCB stands for miniature circuit breaker mcb is an electrical switch that is automatically controlled to protect an electrical circuit from damage caused by excess current from overload or short circuiting mcb are not typically lost during overcurrent and they can be reused.
