1 Main Purpose and Scope of Application
DZ47sLES series residual current operated circuit breaker (hereinafter referred to as leakage circuit breaker) has electric leakage (electric shock), overload, and short circuit protection functions, and can also have over-voltage and under-voltage protection functions according to the needs of users.
DZ47sLES leakage circuit breaker is used in the AC 50/60Hz lines with rated voltage 230V/400V and rated current up to 63A for indirect contact protection of people, as well as overcurrent protection for buildings and similar lines. It can also provide protection against fires caused by persistent earth faults due to the non-operation of the overcurrent protection device. Leakage circuit breakers with overvoltage protection can also provide the production against excessive voltage increases due to grid faults.
This series of products has been increasingly used in low-voltage power distribution systems as a backup protection against earth faults, direct contact and indirect contact electric shocks.
The circuit breaker is equipped with 6 different accessories, including: OF auxiliary contact, MX+OF shunt releases, SD alarm contact, MV overvoltage release, MN undervoltage release and MVMN overvoltage and undervoltage release. When there are multiple accessories installed, the size for maximum number of installations is less than 54mm.

Table 5 Fault and troubleshooting
Fault Cause Solution
M i s -o p e r a t i o n
Mis-operation caused by zero line earthed at the load side of the residual current operated circuit breaker When the zero line on the load side of the residual current operated circuit breaker is earthed, the normal operating current will flow in through the earth point to cause mis-operation.
Residual current operated circuit breaker
Incorrect wiring
Connect the earth wire to the zero line at the power side of the residual current
operated circuit breaker
Residual current operated circuit breaker
Correct wiring Mis-operation by
the leakage current and the current of
the wire to
capacitor
Wire on the load side is laid tightly on the
ground too long
Select the residual current operated circuit breaker with a large residual operating current The leakage current of the wire on the load
side to earth is increased due to insulation
reduction.
Replace wire
