Chint NL1-63-263/100 RCD – 2P – 63A – 100mA
Chint NL1-63-263/100 residual current device, a 63 A 100 mA 2 pole AC type RCCB for earth leakage protection in consumer units, distribution boards and industrial electrical installations.
Why Choose the Chint NL1-63-263/100 Residual Current Device?
The Chint NL1-63-263/100 is a dependable residual current device (RCD) designed to provide earth leakage protection in residential, commercial and light industrial electrical installations. As part of the Chint NL1 RCCB series, it automatically disconnects the circuit when residual current faults are detected, helping protect people, equipment and property from electric shock and fire hazards.
This device is a 2 pole, AC type RCD suitable for detecting sinusoidal alternating residual currents. It is commonly installed in consumer units, distribution boards and electrical control panels where reliable residual current protection is required without integrated over-current protection.
With a rated current of 63 A and a residual operating current of 100 mA, the NL1-63-263/100 provides dependable earth leakage protection for higher load circuits. Its DIN rail mounting format enables straightforward installation into modern electrical enclosures.
Key Advantages
- Reliable 2 pole residual current device for earth leakage protection.
- 63 A rated current for higher capacity electrical circuits.
- 100 mA residual operating current for leakage fault detection.
- AC type RCD for sinusoidal alternating residual current protection.
- DIN rail mounting for fast installation in consumer units and distribution boards.
- Helps reduce electric shock risk and fire hazards caused by insulation faults.
Key Features
- Chint NL1 series residual current circuit breaker.
- 63 A rated current.
- 100 mA residual operating current.
- 2 pole configuration.
- AC type tripping characteristic.

Reliable Earth Leakage Protection for Electrical Installations
Residual current devices such as the Chint NL1-63-263/100 continuously monitor the difference between live and neutral current. When an earth leakage fault occurs, the device disconnects the circuit rapidly to help protect users from electric shock and reduce the risk of electrical fires caused by insulation faults.
The NL1 series is designed to provide residual current protection only and should be installed alongside suitable over-current protection, such as an MCB or fuse. Its compact DIN rail format makes it suitable for residential, commercial and industrial electrical installations.
Typical Applications
- Consumer units and distribution boards.
- Residential electrical installations.
- Commercial building circuits.
- Light industrial power distribution.
- Earth leakage protection for final circuits.
- Electrical panels requiring dedicated residual current protection.
