Wabco 4492440550 Power Cable 5.5M

Description

The Wabco 4492440550 Power Cable 5.5M is a critical component within air brake systems, specifically designed for EBS (Electronic Braking System) applications. This cable facilitates the power connection between the tractor and trailer, ensuring reliable communication and functionality of the braking system. It features a socket ISO 7638 7-pin + diagnosis socket with blue cap 7-pin on one end and an X1 power 8-pin connector on the other. Measuring 350 x 350 x 90 mm, this OE specification cable is engineered to deliver consistent performance and durability, contributing to enhanced safety and operational efficiency within commercial vehicle braking systems.

Key Features & Benefits

This cable is pretty straightforward – it delivers electrical power from your truck's electrical system to the trailer brake controller itself. It also carries the signal from the controller to the trailer's brakes. It’s basically the communication line and power supply all rolled into one. It’s a multi – purpose cable, handling both the juice to run the controller and the information that actually tells your trailer brakes when and how hard to apply. Think of your brake controller as the brain, and this cable as the spinal cord connecting it to the trailer's braking muscles. Without a solid connection, the brain can't tell the muscles what to do. It runs from your truck's power source, usually somewhere near the driver’s seat, all the way back to where the trailer connects. It’s a dedicated line, so it doesn't share space with any other electrical functions.

Symptoms, Risks & Replacements

Honestly, this is a safety item. If this cable is damaged, frayed, or has a poor connection, your trailer brakes might not work properly, or not at all. You’ll notice if it’s completely failed—you’ll likely have zero trailer braking. But even partial issues can be really dangerous because it can cause delayed response or inconsistent braking. That extra stopping distance, even a few feet, can make all the difference. A good, solid cable acts like a shield, ensuring a reliable signal and power delivery. We carry these at Fixparts Online, and a replacement is cheap insurance compared to the cost of an accident. It's worth checking this cable regularly for wear and tear, especially if you do a lot of towing.
