Roll Over to Zoom

The HWA20 is a compact hard-wired fuseholder that holds up to 10 ATO fuses. The input and output connections are electronically isolated, enabling the user to customize the circuitry. Littelfuse ATO blade fuses provide a versatile fusing capability, as they are readily available in a wide range of values from 1A to 40A.

  • The compact unit measures 161 x 40 x 52mm (6.3 x 1.6 x 2.0”) and contains a high density of fuses, with total combined amperage up to 210A. Perfect for accessory circuits, overflow circuits from main power distribution module, or as a main module on smaller vehicles.
  • Unit is sealed to IP67 and is constructed from extremely durable polyamide.  These sealed units can be installed virtually anywhere on a vehicle, and stand up to roadsplash and salt spray.
  • Dovetail slots on the sides enable multiple units to be physically connected to each other, to easily expand circuit protection capacity. They can also be interlocked with Littelfuse PDMs and fuseholders such as FLEC Power Distribution Module, HWB60, HWB18, MEGA-Flex and MIDI-Flex.
  • Units are easy to connect - wires plug into the back of the unit using industry-standard Tyco sealed power terminals. The terminal position assurance locks (TPAs) give secondary locking protection of the wire leads, to aid help prevent  leads  being pulled out. TPAs snap onto the back of the unit after wires are installed, and do not interfere with the cable seals needed to ensure IP protection.
