Overview

The Mersen AF2-5 Blade Style Automotive Fuse (SKU: AF2-5) is a precision-engineered circuit protection solution designed for 32V electrical systems requiring a 5-amp current rating. Part of Mersen’s trusted AF2 series, this blade-style fuse delivers reliable performance in automotive, marine, recreational vehicle, and industrial applications where robust overcurrent protection is critical. Engineered to meet the demands of high-vibration environments, the AF2-5 fuse combines durability with fast-acting response to prevent damage from short circuits, overloads, and transient surges. Its compact, blade-style design ensures easy installation in fuse blocks, panels, and distribution systems, making it a preferred choice among technicians and engineers. The 32V rating makes it suitable for 12V and 24V systems with transient voltage spikes, while the 5A current rating provides precise protection for sensitive circuits such as lighting, sensors, control modules, and auxiliary systems. The blade-style construction, featuring a flat, tabbed terminal, ensures secure contact and low contact resistance, reducing the risk of overheating or intermittent failures. This design also facilitates quick replacement during troubleshooting, minimizing downtime in critical applications.
