are current-limiting, high interrupting rating fuses intended for the short-circuit protection of medium voltage motors and motor controllers. r-rated fuses are back up fuses that have a minimum interrupting rating, and must be coordinated with overload relays in combination motor starters. elements...

let us put it this way: this statement is not generally correct; it is roughly true, however, of part of the miniature fuses offered on the market. but let us begin by looking at the problems fuses may encounter in interrupting direct currents. if a short-circuit current flows through a fuse, after a...

also an abnormal power draw from ac caused by an internal fault on ac can cause the fuse to blow. instead of trudging up and down the stairs to reset the breaker or replace the fuse, only to have it trip again, the load on that circuit must be reduced. i went to troubleshoot a motor that is blowing fuses...
