In this clear, concise and well-illustrated PowerPoint presentation, ABB looks again at ‘The Great Debate’ about fuses versus circuit-breakers for protection:
So back to the debate.......which technology is best? Is it the thermally-operated fuse, with its associated fuse switch and switch fuse, or is it the various types of electromagnetic circuit-breaker – the air circuit breaker (ACB), the moulded case circuit breaker (MCCB), the miniature circuit breaker (MCB) or the switch plus relay?
ABB’s presentation looks at the technologies closely and finds that the answer is not simply a matter of one being superior to the other, and that the choice of protective device needs to be considered taking the requirements of the installation and the end client into consideration.
