Our earth leakage circuit breaker is generally composed of a ZCT (Zero-phase-sequence Current Transformer) + Earth leakage relay + Circuit breaker. The ZCT detects earth leakage current, notifies the electronic circuit, and shuts off the circuit using an internal tripping device.
A leakage current of 100 mA or more can cause a fire. An earth leakage circuit breaker detects earth leakage of approximately 15 to 30 mA, and immediately shuts off the circuit within 0.1 seconds, preventing an accident.
The earth leakage circuit breaker (ELCB) is used to protect persons against electric shock hazards and to prevent a fire. This also have the same function as MCCB. This type of breaker is ELCB rated 225 Amp or less, and is available to protect a motor and the associated wiring or conductors.
As shown in the figure below, in cases such as when an electrical device is used in a location where there is humidity or moisture, or when a portable motor-driven appliance is used in a location of high conductivity such as an iron plate or iron frame, an earth leakage circuit breaker is necessary.
