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.
MCB has several advantages over fuse: 1  MCB is more sensitive to current than fuse. It detects any abnormality in the current flow and automatically switches off the electrical circuit. 2  In case of MCB, the faulty zone of electrical circuit can be easily identified. Faulty circuit trips to the off position.
