What is elcb breaker

An ELCB (Earth Leakage Circuit Breaker) is a type of electrical safety device that is designed to detect and interrupt earth leakage currents in an electrical circuit. It is also known as an Earth Fault Circuit Breaker (EFCB).

An ELCB is a type of residual current device (RCD) that is designed to protect people from electrical shock and electrocution. It works by monitoring the current flowing in a circuit and detecting any imbalance between the current flowing to earth and the current flowing in the circuit.

Here's how it works:

  1. The ELCB monitors the current flowing in the circuit and measures the residual current (the difference between the current flowing to earth and the current flowing in the circuit).
  2. If the residual current exceeds a certain threshold (usually set at 30mA), the ELCB trips and interrupts the power supply to the circuit.
  3. The ELCB can also be set to trip at a higher threshold (usually 100mA) to provide additional protection against electrical shock.

ELCBs are commonly used in a variety of applications, including:

  1. Domestic electrical installations: ELCBs are often installed in homes and apartments to provide additional protection against electrical shock.
  2. Industrial electrical installations: ELCBs are used in industrial settings to protect workers from electrical shock and electrocution.
  3. Medical equipment: ELCBs are used in medical equipment to provide additional protection against electrical shock.
  4. Swimming pools: ELCBs are often installed in swimming pools to provide protection against electrical shock.

The benefits of using an ELCB include:

  1. Improved safety: ELCBs provide additional protection against electrical shock and electrocution.
  2. Reduced risk of injury: By detecting and interrupting earth leakage currents, ELCBs can reduce the risk of injury or death from electrical shock.
  3. Compliance with safety regulations: ELCBs are often required by safety regulations and standards, such as the IEC 60364 standard.

Overall, an ELCB is an important safety device that can help protect people from electrical shock and electrocution.
