Description
Littelfuse 229/230 series Slo-Blo® Fuses are available in
2AG size cartridge or axial lead form, offer tripped fuse
indicating option, and offer features designed to meet
rigorous Telecom industry requirements.
229/230 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.
The 229/230 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 60950-1/
UL 62368-1 for telephone equipment. Insulating sleeve
option is also available. R efer to the Surge Withstand
Specifications section of this document for additional
