Features
• 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 short-circuit current.
• Fuses can easily be selectively coordinated when sized
per published coordination ratios.
