• 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.
