Chint Residual current device NL1-63 40A 4P 30MA AC Type 4 Modules 200224

The Residual current device is used to protect people, not systems. The moment the person goes to touch it, it creates a circuit with the ground. The current instead of staying in the household circuit, uses the human body to go to ground.

 

The residual current device, also called a circuit breaker, is a device in your electrical system. It is capable of opening the circuit, that is, shutting off the power supply, the moment the current accidentally dissipates.

 

A Residual current device offers protection in case of current leakage but not in case of overvoltage. Instead, the circuit breaker is required for this type of problem.

 

The AC-type earth leakage circuit breaker, works only with alternating current. Almost all installations for civil use fall into this type.

 

The pure earth leakage circuit breaker series NL1-63, without built-in overcurrent releases, for the protection of users against direct and indirect contacts.
