What is ELCB? What is the effect of the water heater?

Water heaters use electricity to heat water, so the integration of ELCB is essential to ensure safe use and concern for users. So what is ELCB, what effect does it have in a water heater, let’s find out in this article!

What is ELCB?

ELCB (short for Earth leakage circuit breaker), is a device placed inside a water heater, commonly known as an ELCB.

This breaker has the function of disconnecting the device from the electrical circuit whenever there is an electrical leakage through the human body when touching the electrical network parts of the device.

The water heater is equipped with an ELCB to limit electrical incidents inside the machine, disconnect the power when there is a problem, ensure safety for human life as well as prevent fire and explosion.

Structure of ELCB and principle of operation of ELCB

ELCB has the same structure as an aptomat, but inside the ELCB will have an additional circuit that compares the current passing through it towards the device that is trying to consume electricity.

ELCB works based on comparing currents in the direction of going and going in each cycle to detect the difference in power with each other.

If there is too high a current difference (greater than 10A ), the ELCB will automatically cut off current through an inductive coil with all phase wires (including neutral if any) going through the ELCB.

Advantages of using water heaters with ELCB . installed

When buying a water heater, you need to choose a machine with an ELCB system installed with many outstanding advantages such as accident prevention, power interruption when problems occur, helping to ensure maximum safety for users.

When buying, it is important to pay attention because there are many machines on the market that are not equipped with ELCB leakage protection system, but instead use an anti-shock CB (Aptomat) to cut costs for the machine, but CB only has an effect. Used when a short circuit occurs with a current greater than the rating.

It is recommended to choose a machine with an ELCB device installed, so that you can minimize short-circuit incidents and detect problems when the leakage current is small. When a leak occurs, the ELCB will cut off the power immediately to warn the user about unsafe power and to avoid fire, explosion, and short circuit.

Uses of ELCB on water heaters

Normally, the ELCB is installed inside the water heater, however, to be safer, you can also install an ELCB next to the water heater, especially the direct water heater, specifically:

• Limit the phenomenon of electric shock inside the device, because the ELCB has high sensitivity to limit the electric shock inside the machine.
• Automatically cut off power when there is a problem, ensuring the safety of users, when detecting leakage current flowing in an electrical circuit.
• Prevention of fire and explosion hazards.
• To ensure the safety of users, when you want to use the water heater again, the switch must be turned on again.

Note when using a hot water bottle for safety

The water heater is equipped with a highly secure anti-shock system, but the risk of an accident can still occur, so you should pay attention to a few things to prevent dangerous incidents:

• Install electrical safety devices including: aptomat, ELCB equipment and ground wire, to ensure maximum safety when using. You should regularly check by inserting an electrical tester into the water line or directly into the water.
• When in use, the water heater automatically cuts off the power, you should not turn it back on, but check the heating system for electrical leakage.
• Should turn on the machine before 8-10 minutes and then disconnect, avoid turning on the device when taking a shower because of the potential risk of electrical accidents.
• Not turning on the machine 24/24, both wastes power and makes the machine work continuously, prone to errors that cause electrical leakage, affecting the safety of consumers.
• Regularly maintain and maintain the water heater to ensure electrical safety, avoid the risk of leakage, fire and explosion.
• Buy water heaters from reputable brands with good product quality to ensure safety when using.

Hopefully with the above information from Tnhelearning.edu.vn, you have a better understanding of how ELCB plays a role in water heaters. So, choose to buy a water heater with an ELCB installed inside to protect you and your family members!
