An ELCB is an Earth Leakage Circuit Breaker and is a device used for safety purposes to detect stray voltage or current on a metal enclosure in order to prevent shock. The two types of ELCB are Voltage-operated and current-sensing protection. The difference between a 30mA ELCD and a 300mA ELCB is that the 30mA version will have a much higher level of sensitivity, tripping the device is a much lower current.
Voltage-ELCBs were first introduced about sixty years ago and Current-ELCB was first introduced about forty years ago. For many years, the voltage operated ELCB and the differential current operated ELCB were both referred to as ELCBs because it was a simpler name to remember. But the use of a common name for two different devices gave rise to considerable confusion in the electrical industry.
To size an Earth Leakage Circuit Breaker (ELCB) for a motor, first determine the motor's full-load current (FLC) by consulting the motor's nameplate or using relevant formulas based on its power and voltage. The ELCB should typically be rated for a sensitivity level appropriate for the application, commonly between 30 mA and 300 mA for motors, depending on safety requirements. Additionally, consider the motor's starting characteristics, as inrush current can be significantly higher than the FLC; hence, select an ELCB that can handle these surges without nuisance tripping. Always refer to local electrical codes and standards for specific requirements.
An Earth Leakage Circuit Breaker (ELCB) and a Residual Current Device (RCD) serve similar safety functions by protecting against earth faults, but they operate differently. ELCBs are older devices that detect earth faults through voltage monitoring, while RCDs detect imbalances in current flow. Generally, RCDs are considered more reliable and are widely used today. Therefore, while you can replace an RCD with an ELCB in some cases, it's advisable to use RCDs for better safety and compliance with modern electrical standards.
To replace a fuse in an ELCB (Earth Leakage Circuit Breaker), first turn off the main power supply to ensure safety. Open the ELCB cover, locate the blown fuse, and carefully remove it. Insert a new fuse of the same rating, ensuring it fits securely, and then close the cover. Finally, restore power and test the ELCB to confirm proper operation.
Take a wire and ground the neutral at the load point. Some current will leak through ground and the same will be sensed by elcb and trip. Other method is simply test a lamp across phase and earth with out using neutral.elcb should trip if it is functioning correctly.

it came to india from africa
elcb is the daughter of ELR ,mcb is their one onlyn son

Earth Leakage Circuit Breaker(ELCB) was given to a device that breaks the power supply when a fixed amount of current ,say 25-40 milli amperes flow through the earth line. The MCB (Miniature Circuit Breaker) is a device designed to protect a circuit's wiring from the serious damage which would be caused if it has to carry a current which is too high for the diameter of the its wire
a pir sytem dectects heats and movement so basically like an alarm system!
