info

Thanks to electronically isolated input and output connections, the HWA20 Series 32V Hard-Wired Waterproof ATO® Fuse Box allows you to achieve customized circuit protection with up to 10 ATO® blade fuses (sold separately).

This compact, IP67-rated waterproof fuse holder is dust-tight and protected against temporary immersion in water, which means it can be installed nearly anywhere on a vehicle.

Plus, if you ever need to expand a vehicle's circuit protection capacity, the HWA20 Series modular fuse block can be connected to additional units or compatible power distribution modules and fuse holders, including FLEC, HWB60, HWB18, MEGA® Flex, and MIDI® Flex models.

  • Compact, 20-cavity hard-wired fuse box fits 10 ATO® blade fuses (sold separately)
  • Handles 40A continuous current per circuit and 210 maximum continuous current overall
  • Sealed, IP67-rated, waterproof fuse holder can be installed virtually anywhere on a vehicle and stands up to road splash and salt spray
  • Dovetail slots on the sides make it a modular fuse box that can be connected to other fuse holders to easily expand circuit protection capacity
  • Wires plug into the back of the unit using industry-standard Tyco sealed power terminals, making the fuse box easy to connect
  • Terminal position assurance (TPA) locks help prevent disconnection of wires due to vibration and accidental snagging
