Product Description

Product Description

STF7 Series Circuit Breaker 10ka 2P 4P 63A RCCB
General

STF7 Residual Current Circuit Breaker(without over-current protection) is suitable for the line of AC 50/60Hz, voltage 240V(2pole) / 415V(4pole), rated current up to 63A.When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will cut off the power rapidly to infrequent chageover of the line in normal situation. And it is application to industrial area, commercial area, tall buikding and civil house, which complies with standard IEC/EN61008.1 and GB16916.1

Product Over View:

1.Provide protection against earth fault/leakage current and function of isolation

2.High short-circuit current withstand capacity

3.Applicable to terminal and pin/fork type busbar connection

4. Equipped with finger protected connection terminals

5.Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity

6.Independent of power supply and line voltage, and free from external interference, voltage fluctuation.
