A1, compared with the maxiumum preferred rating of 20A. Such fuse link ratings are defined in BS 88: 1975 as motor cir- cuit fuse links and they have a dual basis of rating, namely a given rating with respect to their ability to carry current continuously, and a larger current rating with respect to their time/current characteristics. For example a TIS63M100 has a continuous current rating of 63A, but the time/current characteristic of a 100A fuse link. These fuse links fulfil a useful purpose in enabling economies to be made in the sizes of associated equipment, e.g., a 30kW, 415V, direct-on-line 3-phase induction motor has a full load current of 55A, but its starting surges are such that it needs a 100A fuse link to withstand them (see page 14). This motor can therefore be protected by TIS63M100 fuse links in Red Spot 63A fittings. Had the motor circuit rating fuse not been available it would have been necessary to use TCP100 fuse-links in Red Spot 100A fittings. A motor circuit fuse link must not be run continuously at any load current in excess of the smaller of its dual current ratings.
