The 382 TR-5 Series subminiature fuse meets the
following safety standard (IEC60127-3/IV) and is VDE & SEMKO
approved and cULus recognized. Fuses are used in electronic lighting
ballasts to protect against overcurrent and short circuit fault
conditions. When individual lighting ballasts are protected, the faulty
ballast is easily identified and prevents an entire string of ballasts
from going off. This serves to not only reduce the labor costs in
identifying the faulty ballast but also prevents a dangerous situation
where large areas such as an office complex or factory floor could be
"blacked out". U.S. commerical buildings typically operate with a line
voltage of 227 Vac plus a 10% safety factor requiring protection
components to be rated greater than 305V. The 382 Series TR-5 is
certified up to 320Vac and is designed for use in board assembly
processes. Due to its inherent small form factor, costs are optimized
while space saving designs are possible.
