CHINT NB2LE Residual Current Operated Circuit Breaker,
provides combined protection against overload, short-circuit, and residual current faults in AC 230/240 V circuits.
Designe for industrial, commercial, and residential applications, it automatically disconnects the power supply upon leakage or electric shock,
ensuring maximum safety. With 6 kA breaking capacity, multiple tripping curves,
and leakage sensitivities from 30 to 300 mA, the NB2LE is reliable, compact, and compliant with IEC/EN 61009-1 standards.
