DESCRIPTION

DZ47 LE Miniature Leakage Circuit Breaker

Scope of application

DZ47LE series miniature leakage circuit breaker is applicable to AC 50Hz or 60Hz lines
with rated voltage of 220V for the single-pole two-wire and two-pole, and 380V for the
three-pole, three-pole four-wire and four-wire, and rated current up to 63A. When personal
electric shock or power grid leakage current exceeds the specified value, the residual current
actuates the circuit breaker, which can quickly cut off the fault power supply in a very short time
and protect the safety of personal and electrical equipment. The residual current operated cir-
cuit breaker has overload and short circuit protection functions, which can be used to protect
the line or motor from overload and short circuit, and can also be used for infrequent switching
and starting of the line under normal conditions.
Standard: GB16917 1, IEC 61009-1.

Normal operating conditions

The ambient temperature is -5°C-40°C, and the average temperature within 24 hours shall not
exceed 35°C;
Altitude: the altitude of the installation site shall not exceed 2000m;
Installation category: level II and III;
Pollution level: Level 2;
Installation conditions: the external magnetic field of the installation site shall not exceed 5
times of the geomagnetic field in any direction.

Classification by the characteristics of instantaneous release: type C (5-10) In, type D (10-16) In.

Main technical parameters:

Rated voltage Un (V): 220V for the single-pole two-wire and two-pole;
380V for the three-pole, three-pole four-wire and four-pole;
Rated short circuit capacity lcn(A)
For frame size with current of 32A:
4000For frame size with current of 63A: 3000
Rated residual making and breaking capacity l△m (A): 2000;
Rated residual non-operating current l△no: 0.5l△n;

Mechanical and electrical life:

a.Electrical life:2000,cos o= 0.85-0.9;
b.Mechanical life: 2000 times;
c. Operating frequency: Ins25A, 240 times/h; In>25A 120 times/h;
Insulation impulse voltage resistance
a. Each pole is connected together with the neutral pole and can withstand an impulse voltagewith a péak value of 6000V
b. Between poles connected with the neutral pole and the metal support, it can withstand an impulse voltage with a peak value of 8000V.
The residual current operated circuit breaker has bearing capacity when the peak current is 200A impulse current and does not cause misoperation.
The torque of wiring screw shall not be less than 1.5N*m.
