CHINT NXBLE-32 1P+N 63A RCBO Earth Leakage Circuit Breakers With Leakage Protection
৳ 950.00
Circuit breaker Operated Circuit Breaker with over-current protection (Electronic)
General rules for choosing RCBO:
Rated residual operating current In 30 mA: additional protection in the case of direct
contact In 300 mA: preventative fire protection in the case
of ground fault currents
b.Tripping class AC class Tripping is ensured for sinusoidal, alternating currents, whether they be quickly applied or slowly increase.
c.Tripping curve
C curve (5-10 In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.
D curve (10-14 In) protection and control of the circuits against overloads and short-circuits; protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps).
