Why Choose the CHINT NM1TL-063/4/X2/T1 Enclosed ELCB?
The CHINT NM1TL-063/4/X2/T1 is an enclosed 63 A four-pole earth leakage circuit breaker designed for three-phase, four-wire low-voltage electrical installations. Built around CHINT moulded case earth leakage protection technology, the assembly provides a practical solution where circuit protection and residual current protection are required within a dedicated enclosure.
With a 63 A rated current and four-pole configuration, the NM1TL-063/4/X2/T1 switches all three phase conductors and the neutral. Its earth leakage protection is designed to detect residual current caused by current flowing to earth, providing an additional level of protection for compatible electrical distribution circuits and connected equipment.
Supplied as an enclosed ELCB assembly, the NM1TL-063/4/X2/T1 is suitable for professional commercial and industrial installations where a complete protective solution is preferred over specifying a standalone breaker and separate enclosure. The four-pole arrangement makes it particularly appropriate for three-phase systems requiring simultaneous switching of the phase and neutral conductors.

Four-Pole Earth Leakage Protection
Earth leakage protection is used to detect an imbalance between current flowing through the live conductors and current returning through the circuit. An imbalance can indicate current leaking to earth through equipment, insulation or another unintended path. An ELCB can disconnect the protected circuit when qualifying leakage conditions are detected, helping improve electrical system protection.
The four-pole configuration of the CHINT NM1TL-063/4/X2/T1 makes it suitable for three-phase, four-wire installations where the neutral needs to be switched together with the three phase conductors. Its enclosed construction provides a convenient packaged solution for distribution, machinery and other compatible low-voltage electrical applications.
