Dimensional Data

General Information:

• Current-limiting devices designed specially for use on welder

circuits only.

• Time-current characteristics are designed to hold on the inter-

mittent overloading encountered in welder operation, while pro-

viding 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.
