Medium voltage distribution systems often require special types of over-current protection. Current-limiting power fuses are widely used in these applications because they afford excellent over-current protection and noiseless operation, and can be used in confined spaces.
By limiting the let-through energy at the fault, properly applied current-limiting fuses assist in limiting or preventing short circuit damage to busways, circuit breakers, switches and other electrical components. Current-limiting power fuses are manufactured in ratings ranging from 0.6kV through 38kV and in continuous current ratings from 0.5 amperes through 900 amperes. Various designs are available for use with motors, transformers, capacitors and circuit protection equipment.
