CHINT NXBLE-32 3P+N 6A 10A 16A 20A 32A Earth Leakage Circuit Breaker ELCB
dz47le earth leakage mini 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).
