• Single element, current limiting fuses provide superior short-circuit protection. • Protects low interrupting capacity circuit breakers. Limits the short-circuit current to meet the interrupting capacity requirements of existing equipment. • On older systems available short circuit current may exceed the interrupting capacity of the circuit breakers, fuses can be installed in series with existing equipment. • Well suited for lighting and heating circuits and other non-inductive loads. • Provides component short-circuit protection in compliance with NEC 110-10, where protection devices shall clear a fault without “extensive damage” to the circuit components. • High interrupting rating helps meet the requirements of future system expansion and the increases in available utility shortcircuit current. • Fuses can easily be selectively coordinated.
