ELCB stands for - We can think of electrical energy as a double-edged sword that can be both beneficial and harmful to us if we are not careful. Unfortunately, there are still many people who do not pay attention to the safety of the electrical system at home.
Even though the number of fires caused by electric currents that occurred in Jakarta in 2016 reached 73%.
Besides being the cause of fire, electric current is also very dangerous for the human body. An electric current flowing in the human body of 80mA can cause heart problems that can lead to death.
In fact, according to Law No. 30 Article 29 of 2009, consumers are required to carry out security against the dangers caused by the use of electric power.
Prevention of the flow of electric current through the bodies of humans and pets, requires additional tools besides the MCB, namely the ELCB.
Earth-Leakage Circuit Breaker (ELCB) is an electrical safety device from the risk of electric current leakage. Ordinary ELCBs can be found inside electrical panels, just like MCBs. At first glance, ELCB is similar to MCB, but ELCB and MCB have different functions.
MCB functions as protection in case of overload or short circuit. While the ELCB serves as protection in case of leakage of electric current / electrocution.
ELCB works by detecting an unbalanced electric current. For example, when a person touches an exposed electrical wire from an electrical appliance that is on, an electric current will leak and flow through that person.
The ELCB will immediately detect this leakage current by comparing the electric current flowing in phase and neutral, which turns out to be unbalanced, so it will activate the relay to trip/switch off.
ELCB has several sensitivities:
- 10 mA for protection with high sensitivity requirements, for example for hospitals
- 30 mA for protection against humans / direct contact
- 300 mA for fire protection / indirect contact
Schneider Electric has 2 ELCB products:
ELCB Domae
- Suitable for homes and apartments
- Has 2 types of sensitivity: 30 mA and 300 mA
Acti9 ilD
- Suitable for industrial and high sensitivity needs (such as hospitals)
- Has 3 types of sensitivity: 10 mA, 30 mA, and 300 mA
These two ELCB products from Schneider Electric are in accordance with the SNI IEC 61008-1:2017 standard, so they are safe to use.
