Why Choose the CHINT NM1TL-100/3/X1/T1 Enclosed ELCB?
The CHINT NM1TL-100/3/X1/T1 is a 100 A three-pole enclosed earth leakage circuit breaker designed for low-voltage commercial and industrial power distribution applications. Part of the CHINT NM1TL enclosed ELCB range, it combines moulded case circuit protection with adjustable residual current protection in a dedicated enclosure.
Rated at 100 A, the three-pole device provides protection for three-phase circuits while the integrated earth leakage function detects residual current caused by leakage to earth. The X1 residual current setting is adjustable between 0.05, 0.1, 0.2 and 0.5 A, allowing the protection level to be configured for the requirements of the installation.
The T1 time-delay setting is also adjustable at 0.1, 0.3, 0.5 or 1 s. Supplied in an enclosure measuring approximately 500 mm high, 400 mm wide and 150 mm deep, the NM1TL-100/3/X1/T1 also features a removable bottom gland plate and can be padlocked in the OFF position for secure isolation during maintenance.
Key Advantages
- Complete 100 A three-pole enclosed ELCB for low-voltage distribution.

Adjustable Earth Leakage Protection for Three-Phase Circuits
Earth leakage protection monitors the protected circuit for an imbalance that indicates current is flowing through an unintended path to earth. Combining this functionality with moulded case circuit breaker protection provides a practical solution for three-phase distribution circuits where both conventional overcurrent protection and residual current monitoring are required.
The X1 and T1 adjustments allow the NM1TL-100/3/X1/T1 to be configured for different installation requirements. Residual operating current can be selected from 0.05 to 0.5 A, while the time delay can be selected from 0.1 to 1 s, providing greater flexibility than a fixed-sensitivity earth leakage device.
Typical Applications
- Three-phase commercial electrical distribution.
- Industrial power distribution systems.
- Machinery and equipment supplies.
- Control panels and switchboard circuits.
- Incoming and outgoing distribution feeders.
- Circuits requiring adjustable earth leakage protection.
- Local enclosed circuit protection and isolation.
