Why Choose the Chint NL1-100-2100/30 Residual Current Device?

The Chint NL1-100-2100/30 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, equipment and property from electrical 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 dependable residual current protection is required without integrated over-current protection.

With a rated current of 100 A and a residual operating current of 30 mA, the NL1-100-2100/30 provides high-sensitivity earth leakage protection for higher capacity single-phase circuits. Its DIN rail mounting format enables quick, neat and secure installation in modern electrical enclosures.

Reliable Earth Leakage Protection for Electrical Installations

Residual current devices such as the Chint NL1-100-2100/30 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 hazards 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 higher capacity final circuits.
• Electrical panels requiring dedicated residual current protection.
