EATON CLS current limiting fuses are used in conjunction with medium voltage motor starters to provide short-circuit protection for individual motor circuits. Contactors in motor starting equipment protect the equipment from over currents due to starting, stalling and plugging while current limiting fuses provide short-circuit protection only. Duty cycles of fuses used in medium voltage motor starters are characterized by the frequent application of high overloads such as motor starting currents. Motor starter fuses, therefore, must be designed to withstand the consequent frequent severe heating and cooling cycles without fatigue failures. CLS type fuses have such a construction. The element designs used are not sensitive to low currents, and have fatigueproof features to provide highly uniform flexing of elements during heating cycles.
