ELCB is an acronym for Earth leakage circuit breaker, which is a device placed inside a water heater, commonly referred to as ELCB electric leakage breaker. This circuit breaker has the function of disconnecting the device from the circuit whenever an electrical leak occurs through the human body when touching the electrical parts of the device.
ELCB is to limit the incident of electric shock inside the machine, disconnecting the power when there is a problem, ensuring safety for human life as well as fire and explosion prevention.
ELCB is often used in both civil and industrial applications.
For the domestic electricity system, the installation problem is not difficult, but in industry, the anti-shock for workers and the prevention of electrical leakage for electrical equipment with large capacity requires a bridge. Automatic anti-shock, high-power leakage protection, and often has a much higher price.

Arrange 1.16 billion yuan of investment in the central budget.
Second, support key projects for resource conservation and recycling, including: water conservation, comprehensive utilization of resources, remanufacturing, “zero†emissions, and 143 key projects of the national circular economy pilot units, with a total investment of 15.19 billion yuan, arranging central budget investment 8.3 100 million yuan. After the project is implemented, it can form a water saving capacity of 21 million tons, and the waste recycling capacity can reach 4.8 million tons. The third is to support industrial pollution control projects in key river basins.
In addition, the 1 billion investment for the construction of grain and oil storage facilities and drying equipment, and the 29.1 billion investment for agriculture, forestry and water conservancy projects have also been completed. 
How many types of ELCB?
According to the official website of the National Development and Reform Commission, in the new 100 billion yuan of central investment this year, the “Top Ten Key Energy-Saving Projects, Circular Economy and Key Basin Industrial Pollution Control Projects†have arranged a total of 2.5 billion yuan of central budget investment, involving 468 projects. According to reports, these 468 projects mainly include the following three aspects:
