The following curves show the total fault current breaking time, depending on its amperage. For example: based on the curve on page 3, an iC60 circuit breaker of curve C, 20 A rating, will interrupt...
In/Io คือ Rated operational current พิกัดกระแสทำงานปกติ โดยที่ breaker ไม่ตัดวงจร Ir คือ Long-Time Overcurrent Protection กระแสที่ตั้งให้ตัวป้องกัน overload = ค่ากระแส overload จะไม่ทำให้ breaker...
IEC 60947-2 has been around a while. Originally called IEC 947-2, it got its current name way back in 1997. So, you may wonder, why talk about it now? Let’s say a timely reminder is about due....
