HWB60-SEALED HARD-WIRED MODULES (MINI STYLE)
Description
The HWB60 is a hard-wired module for use with 280 style
components (i.e. mini-fuses, relays, diodes, resistors, etc.) It
features 60 cavities creating a high density fuse module with a
compact footprint. Without internal bussing, it allows the flexibility
of custom circuitry by the end user. Wires simply plug into the
back of the module using sealed Delphi Metri-Pack Series 280
tanged terminals.
Sealing in the cover and around the wires allow for use in extreme
environments. Dovetail features on the sides of unit allow the user
to stack multiple HWB60’s together to increase their circuit
protection package. These same dovetails can also be used to
attach an add-on component that holds a fuse puller and spare
fuses. Cover tethers and TPAs (terminal position assurance locks)
are also available.
Alternative component footprints may be available. Contact
Littelfuse for more information.
