Safety Breaker. Suppose human body resistance is 500ω and voltage to the ground is 230 volt. Elcb earth leakage circuit breaker phase line neutral and earth wire connected through elcb.
Elcb is working based on earth leakage current. Industrial circuit breakers in themselves are safety devices because they work to cut off the power to a building when there is too much of an electrical current flowing through the wires. If the current goes beyond the capacity of the wire omni circuit breaker play its essential part by stopping the electrical current before the wire overheats and cause fire.
In a nutshell safety switches protect lives by turning the power to the circuit off.
The safest limit of current which human body can withstand is 30ma sec. In a nutshell safety switches protect lives by turning the power to the circuit off. Circuit breakers are designed to detect faults in electrical currents that flow to every room and outlet in your home by automatically switching electricity off during a power surge like an arc fault breaker. This prevents a power surge that could lead to fires or the destruction of appliances.
