Bussmann® Welder Limiters 68000 & 64000 Series Class H and J Fuseholders General Information: • Current-limiting devices designed specially for use on welder circuits only. • Time-current characteristics are designed to hold on the intermittent overloading encountered in welder operation, while providing short-circuit protection to the circuit and equipment. • Welder limiters have excess current capacity in the operating range as needed for this type of service. • Because of the special characteristics of the welder limiters, they are not intended for application on general-use circuits.
