Cooper Bussmann's cable limiters protect low-voltage grid network and service-entrance cables-in residential and light commercial applications up to 250V AC as well as commercial and industrial applications up to 600V AC for both copper and aluminum cables-from short-circuit currents. They provide current limiting short-circuit protection in single or multicable per phase applications and a means to isolate faulted cables in multicable per phase service-entrance or grid-network applications.
