Provides 10X better current limitation to help
prevent equipment damage caused by short-
circuit events.
200 kA Interrupting rating complies with NEC
®
Section 110.9 for today’s large capacity systems.
Fast-acting fuse helps prevent equipment
damage caused by short-circuit events.
Small, space-saving fuses provide a high
degree of current limitation on short-circuits for
excellent component protection.
Ideal for critical industrial or commercial
applications that have specific current limitation
requirements.
