Performance of microkernel vs monolithic kernel. As is always the answer (or at least the preface) to performance-related questions: know your problem domain, run comparative benchmarks, and remember what premature optimization is.
A summary of the difference between contactors, motor starters, relays and circuit breakers. Switches, circuit breakers, and contactors are used to control what parts of an electrical system are energized or de-energized. Fuses are used to protect the electrical system when something goes wrong, and can isolate the faulted parts from the normal parts.
The only difference between the TL and the SL fuses are the types of bases. The TL fuse uses an Edison base and the SL fuse uses a Rejection base. These fuses work by having a plug of heat-absorbing solder attached to the center of the fuse element.
