10843861

Overview

The Littelfuse 10843861 is a configurable DC power distribution module (PDM) designed for commercial vehicles. It functions as a dust-tight and waterproof electrical center, accommodating multiple automotive fuses, diodes, and relays within a single unit. The module features internal bussing and pre-connectorized interfaces to coordinate circuit protection and current flow efficiently. Constructed with an integrated printed circuit board (PCB), it supports both conventionally-fueled and battery-powered vehicle architectures. This robust design ensures reliable performance in harsh operating environments typical of heavy-duty commercial applications.
