General Information:

• Single-element, current-limiting fuses provide superior short­circuit 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 non­inductive 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 be selectively coordinated with ease.
