NBSe DZ47LE Differential Circuit Breaker, rcbo circuit breaker
1. APPLICATION
Electronic Type Rcbo
Residual current operated circuit breaker DZ47LE series residual current operated circuit breaker is applied to the circuit of AC 50Hz or 60Hz, rated voltage of single electrode two lines, two electrodes 230V, three electrodes four lines, four electrodes 400V, rated current up to 60A; when the human body has electric shock, or the electric leakage current exceeds the set value, residual current operated circuit breaker will quickly cut off the faulted power within a very short period of time failure to protect the personal safety and the safety of electrical equipments. The residual current operated circuit breaker has overload and short circuit protection function, which can be used to protect the overload and short circuit of the circuit or the motor, and can be used as a non frequent switching starting of the circuit under normal conditions.
2. Technical Data
Personnel and fire protection
Cable and line protection against overload and short-circuits
1.2 General rules for choosing RCBO:
a. Rated residual operating current
≤ 30mA: additional protection in the case of direct contact
≤ 300mA: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)
