Quick details
3GM series Slo-Blo® Fuses are available in 3GM size cartridge or
axial lead form, offer tripped fuse
indicating option, and offer features designed to meet rigorous
Telecom industry requirements. 3GM series product ordered with the
tripped fuse indicating option show discoloration of the glass body
immediately after trip. They offer the same performance
characteristics as standard product, and help to reduce time
locating the tripped fuse and troubleshooting circuit
issues.
3GM series 0.25A - 1.25A range combines conventional overcurrent
protection with ability to withstand high current, short duration
pulses which complies to short circuit requirements of UL 1459 for
telephone equipment. Insulating sleeve option is
also available. Please refer to the Surge Withstand Specifications
section of this document for additional information.
