DZ47LE miniature circuit breaker
AC 230/400V Input
Pole No.1P+N,2,3P+N,4
Rated frequency: 50/60Hz
Characteristics
Protection against both overload and short circuit
High short-circuit capacity
Its frame and parts adopt plastics of high fire-resistant and shockproof
small apperance.light weight
comply with the standard IEC60898 and GB10963
General
1. Application:
Personnal and fire protection cable and line protection against overload and short circuit.
2. General rules for choosing RCBO:
a. Rated residual operating current
IΔn≤30mA: additional protection in the case of direct contact;
IΔn≤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-circuit; 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-circuit; protection for circuits which supply loads with high inrush current at the circuit closing(LV/LV transformers, breakdown lamps).
