Always keep the concepts of overload protection, short-circuit protection, and fault protection separate. This applies not only to performing motor calculations, but also to troubleshooting and ...

The 16A overload protection device protects the 14 AWG conductors from overcurrent, while the 40A short-circuit protection device protects them from short circuits. This example illustrates the ...

Transistor VT2 provides short-circuit protection to the load, with red LED D4 indicting an overload. (D2 blows out simultaneously with an overload.) Short-circuit current does not exceed 38 mA.
