D-660 Rev A
XT Series
Power Distribution Module
Fuse block with integrated sealed plug outputs
Littelfuse Commercial Vehicle Products
Useful combination of fusing protects 3 high-amp circuits such as vehicle control modules, inverters, auxiliary circuits, and four ATO
fuses for low-amp circuits including clock memory, alarms, tachograph, and Qualcomm modules.
Ignition protected to SAE J1171 and ISO 8846 for installation in a battery box, or on vehicles carrying hazardous loads.
Water and dust-resistant to IP59K, permitting high temperature, high pressure washing. Provides the bene
fit of a sea
led cover, but
allows water to escape if the cover is mistakenly unsecured. Cover is tethered and is positively secured with two snap-shut latches.
Compact unit (less than 6” x 4” x 1.75”) for multiple installation options.
Tin-plated copper studs provide maximum conductivity and significantly lower contact resistance; stainless steel hardware provides
superior corrosion resistance.
Also available with pre-installed fuses to customer needs.
This product is customer-limited. Please consult Littelfuse CVP for details.
