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.
