Blue Sea 5240 7.5A ATO/ATC Fuse

The Blue Sea 5240 7.5A ATO/ATC Fuse is essential for protecting your marine electrical system from overloads and short circuits. Designed for reliability, this fuse is a critical component for any boat, ensuring that navigation, communication, and engine controls remain operational even in challenging conditions.

This 7.5-amp fuse utilizes the industry-standard ATO/ATC blade design, which is recognized for its consistent performance across marine and automotive applications. The fuse features two flat blade terminals that fit securely into standard fuse blocks, minimizing the risk of vibration-induced disconnections. Each fuse is manufactured to stringent standards, ensuring reliable tripping at its rated amperage to protect downstream components.

Ideal for boaters, fishing guides, and marine electricians, the Blue Sea 5240 fuse is commonly used for mid-load circuits such as bilge pumps, trim/tilt motors, and cabin lighting. Keeping spare fuses on hand is a smart practice, as downtime on the water can lead to costly delays and safety concerns.
