The CHINT NL1-63 Residual Current Circuit Breaker (RCCB) is designed to detect earth-leakage currents and disconnect the electrical supply when residual current exceeds the specified operating threshold. It helps reduce the risk of electric shock and electrical fires caused by earth-leakage faults.
The four-pole configuration is suitable for compatible three-phase, four-wire electrical distribution systems. The NL1-63 range offers different rated-current and residual-current sensitivity options for residential, commercial, and industrial applications.
Available sensitivity options include 30mA and 300mA. These are separate product variants and must be selected according to the intended protection requirement.
Important: An RCCB provides residual-current protection only. It does not provide overload or short-circuit protection by itself and must be coordinated with suitable overcurrent protection.

The 30mA version is intended for applications requiring high-sensitivity residual-current protection, including supplementary protection against electric shock where required by the applicable electrical code.
Typical applications include:
The 300mA version is generally used where residual-current protection is required at a distribution or feeder level, including certain fire-risk protection strategies.
Typical applications include:
Selection advice: A 300mA RCCB is not a substitute for 30mA supplementary protection where the latter is required. For installations using both levels, check discrimination and selectivity between the devices. A time-delayed selective
