Why Choose the Chint NL1-63-225/100 Residual Current Device?
The Chint NL1-63-225/100 is a reliable 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 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 used within consumer units, distribution boards and control panels where dependable residual current protection is required without integrated over-current protection.
With a rated current of 25 A and a residual operating current of 100 mA, the NL1-63-225/100 is suitable for circuits requiring earth leakage protection at a higher sensitivity level than standard fault protection. Its DIN rail mounting format enables straightforward installation in modern electrical enclosures.
Key Advantages
- Reliable 2 pole residual current device for earth leakage protection.
- 25 A rated current for low voltage 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.
- Designed to help reduce electric shock risk and fire hazards caused by insulation faults.
Key Features
- Chint NL1 series residual current circuit breaker.
- 25 A rated current.
- 100 mA residual operating current.
- 2 pole configuration.
- AC type tripping characteristic.
- Residual current protection without over-current protection.

Reliable Earth Leakage Protection for Electrical Installations
Residual current devices such as the Chint NL1-63-225/100 monitor the difference between live and neutral current. If an imbalance is detected, the device disconnects the circuit to help prevent dangerous electric shock and reduce the risk of fire caused by insulation faults.
The NL1 series is designed for residual current protection only and should be used alongside suitable over-current protection, such as an MCB or fuse, where required. Its compact DIN rail design makes it suitable for modern consumer units, distribution boards and industrial electrical panels.
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 separate residual current protection.
