Why Choose the Chint NL1-100-480/100-A RCCB?
The Chint NL1-100-480/100-A is a reliable residual current circuit breaker designed to provide earth leakage protection in low voltage electrical installations. As part of the Chint NL1-100 RCCB series, it detects residual current faults and disconnects the circuit when leakage current is present, helping improve electrical safety in commercial, industrial and three-phase distribution systems.
This model features Type A residual current protection, making it suitable for installations where pulsating DC residual currents may occur. Type A RCCBs are commonly used with modern electrical equipment, electronic power supplies, appliances, EV charging related circuits and control devices where enhanced residual current detection is required.
With an 80A rated current, 4 pole configuration and 100mA residual current sensitivity, the NL1-100-480/100-A is suitable for three-phase circuits requiring Type A earth leakage protection where a higher current 100mA residual current device is specified.
Key Advantages
- Compact RCCB designed for residual current protection.
- 80A rated current suitable for larger three-phase distribution circuits.
- 4 pole switching for three-phase installations with neutral.
- 100mA residual current sensitivity for earth leakage and fire risk protection.
- Type A RCD detects AC and pulsating DC residual currents.
- Suitable for modern commercial, industrial and light power distribution systems.
Key Features
- Chint NL1-100 residual current circuit breaker series.
- 80A rated operational current.
- 4 pole configuration.
- 100mA rated residual operating current.
- Type A residual current protection.
- Designed for low voltage AC electrical installations.
- DIN rail mounted for easy installation in distribution equipment.
- Compliant with recognised RCCB protection standards.
Reliable Type A Residual Current Protection
Residual current circuit breakers monitor the current flowing through live and neutral conductors. If an imbalance is detected, caused by leakage to earth, the RCCB trips and disconnects the circuit to help reduce the risk of electric shock and electrical fire.
The Type A protection of the Chint NL1-100-480/100-A makes it suitable for installations containing equipment that may generate pulsating DC residual currents, such as electronic appliances, control systems and modern power supplies. Its compact modular design allows straightforward integration into three-phase distribution boards and control panels.
Typical Applications
- Commercial distribution boards.
- Three-phase electrical panels.
- Sub-main distribution circuits.
- Industrial control panels.
- Circuits with electronic equipment and appliances.
- Earth leakage and fire risk protection for low voltage circuits.

Frequently Asked Questions
What is the Chint NL1-100-480/100-A used for?
It is used to provide residual current and earth leakage protection in low voltage three-phase electrical installations where Type A RCD protection is required.
What current rating does this RCCB have?
The NL1-100-480/100-A has a rated current of 80A.
What does the 100mA rating mean?
The 100mA rating refers to the residual operating current sensitivity, meaning the device is designed to trip when earth leakage reaches approximately 100mA.
What does Type A mean on this RCD?
Type A means the device is designed to detect both sinusoidal AC residual currents and pulsating DC residual currents.
Does this RCCB provide overload protection?
No. An RCCB provides residual current protection only and should be used with suitable overcurrent protection such as an MCB or fuse.
