The Chint NM1TL-100/4/X2/T1 is a robust enclosed Earth Leakage Circuit Breaker (ELCB) engineered to provide comprehensive protection for low-voltage electrical distribution systems. Combining moulded case circuit breaker technology with integrated earth leakage protection, it safeguards circuits against overloads, short circuits and earth fault currents in demanding commercial and industrial installations.
Designed for dependable long-term performance, the NM1TL series features adjustable earth leakage sensitivity and configurable trip delay settings, allowing engineers to optimise protection for individual installations whilst improving discrimination and reducing unnecessary tripping. The enclosed construction also provides enhanced safety and protection for the installed breaker.
With a 100 A rated current, 4-pole configuration and adjustable 100 mA to 1 A earth leakage protection, the NM1TL-100/4/X2/T1 is ideally suited to industrial distribution panels, commercial buildings, manufacturing facilities and critical power distribution systems requiring reliable earth fault protection.
The Chint NM1TL series combines dependable moulded case circuit breaker performance with integrated residual current protection to deliver comprehensive protection for modern electrical installations. Adjustable protection settings provide greater flexibility when coordinating protective devices across complex electrical systems.
Suitable for industrial control panels, commercial buildings, manufacturing facilities and infrastructure projects, the NM1TL range delivers dependable protection, simple installation and long-term operational reliability.
