Description
This Mercedes battery power distribution box is an original electrical distribution unit for W205 models and carries OEM number A2055402850. Built for the Mercedes W205 platform, it is the main fused power junction that links battery supply to multiple protected vehicle circuits.
Its job is to distribute battery current safely across key electrical systems while protecting those circuits through integrated fusing and power routing. In normal operation, it helps maintain stable voltage supply for essential vehicle functions and supports reliable startup and system communication.
Common signs of a faulty unit include intermittent electrical faults, repeated fuse failure, loss of power to certain circuits, no-crank conditions, charging irregularities, or random warning messages caused by unstable power distribution. Damage from heat, corrosion or overload can also affect internal connections.
This is a used original part, removed from a vehicle and tested for proper function. Match OEM number A2055402850 before ordering. Professional installation is recommended, and inspection of related wiring, fuses and terminals is advisable during fitting.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
