Regarding the selectivity between fuses, the rule of thumb is that upstream fuses will...maybe back-up protection is better through box fuses (BS 1361 or... HRC fuses under short-circuit fault conditions) Explain when you start working...In fact, Figure 3 clearly shows that the pre-arc I2t of the 100A device is larger...
Taking 10 LEDs with a current of 600 mA as an example, if an accidental short circuit occurs, a 1 ampere fuse can well protect the circuit. This is a great...
