CHINT NB1L-20 Residual Current Circuit Breaker(ELM)

CHINT NB1L-20 Residual Current Circuit Breaker(ELM),

first Function Personnel and fire protection: Cable and line protection against overload and short-circuits.
furthermore Selection Rated residual operating current IΔn ≤30 mA: additional protection in the case of direct contact.
Tripping class A and AC class A class tripping is ensure for sinusoidal,
alternating residual currents as well as for pulsed DC residual currents,
whether they be quickly or slowly increase. AC class tripping is ensure for sinusoidal,
alternating residual currents, whether they be quickly or slowly increase tripping curve.
