CHINT NBH8LE Residual Current Operated Circuit Breaker

CHINT NBH8LE Residual Current Operated Circuit Breaker,
with Over-current Protection (Electronic) ensures comprehensive personnel and fire protection by detecting leakage, overload,
and short-circuit faults in electrical systems.
Designe for residential, commercial, and industrial environments, it combines earth-leakage protection,
with C-curve thermal-magnetic over-current protection.
Compact and reliable, it meets IEC/EN 61009-1 standards and delivers up to 20,000 mechanical operations,
making it ideal for safe and efficient low-voltage distribution.
