Why Choose the Chint NL1-100-480/100 RCCB?
The Chint NL1-100-480/100 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.
Designed for use in distribution boards and control panels, this RCCB helps protect against fire risk and insulation faults caused by earth leakage. Its compact DIN rail mounted construction makes it easy to install, while its dependable tripping performance supports safe operation across a wide range of electrical installations.
With an 80A rated current, 4 pole configuration, 100mA residual current sensitivity and AC type operation, the NL1-100-480/100 is suitable for three-phase circuits requiring residual current protection where a higher current 100mA 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.
- AC type RCD for detecting sinusoidal alternating residual currents.
- Suitable for commercial, industrial and light power distribution systems.
Key Features
- Chint NL1-100 residual current circuit breaker series.
- 80A rated operational current.
- 4 pole configuration.

Reliable 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 Chint NL1-100 series is widely used in commercial premises, industrial panels and three-phase distribution systems. Its compact design allows straightforward integration into modern distribution boards, while its reliable residual current protection helps support safer electrical systems.
Typical Applications
- Commercial distribution boards.
- Three-phase electrical panels.
- Sub-main distribution circuits.
- Industrial control panels.
- Machinery and equipment circuits.
- Earth leakage and fire risk protection for low voltage circuits.

Frequently Asked Questions
What is the Chint NL1-100-480/100 used for?
It is used to provide residual current and earth leakage protection in low voltage three-phase electrical installations.
What current rating does this RCCB have?
The NL1-100-480/100 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 AC type mean on this RCD?
AC type means the device is designed to detect sinusoidal alternating residual currents commonly found in standard AC circuits.
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.
