Earth Leakage Circiut Breaker DZ47LE(ELCB)
Scope of application
Earth Leakage Circuit Breaker(ELCB)TLYB1LE-63 is usedfor the protection against electrical leakage in the circuit of 50HZ or 60HZ, rated voltage single-phase 240V ratedd current up to 63A. When somebody gets an electric shock or the residual current of the circuit exceeds the fixed value, the ELCB can cut off the power within the time of 0.1s automatically protecting the personal safety and precenting the equipment from the fault resulted from the residual current. With this function, the ELCB can protect the circuit against overload and short circuit or can be used for the unfrequent switchover of the circuit under normal conditions.
The products conforms to IEC61009-1 and GB16917.1 standard.

2)Rated short-circuit capacity lcn: 4000A(C type), 4000A(D type)
3)Rated residual on and off capacity lm: 2000A
4)Rated residual not operating current lno: 0.5 ln;
5)Rated current operating breaking time(Shown in Table 1)
Over-current pretective characteristic(Shown in Table 2)
3. Machanical and electrical life
A. Electrical life: 2000 times, cosΦ =0.85
B. Machanical life: 2000 times
C. Operating frequency: Ln≤ 25A 240 times/hour; Ln≥ 25A 120 times/hour
4. Insulation impact resistance voltage performance:
A. Each pole and connects together with neutral poles, can withstand 6000V peak of impulse voltage.
B. Each pole connects with neutral poles together and the metal frame, can withstand 8000V peak.
In the circuit with 200A peak, 2.5 peak voltage and surge voltage √ 2 Un, the ElCB has the bearing capacity, and doesnot cause malfunction.
