Sleipner ANL Fuse 80A Slow Blow

The Sleipner ANL 80A Slow-Blow Fuse is a heavy-duty marine fuse designed to protect the main power circuit of Sleipner/Side-Power bow and stern thrusters. It uses the standard ANL bolt-on format, which means it mounts securely between two studs in an ANL-style fuse holder and provides a solid, low-resistance electrical connection.

Because it’s a slow-blow fuse, it can handle the short bursts of high current that electric thruster motors draw when they first start up. These surges are normal and would instantly blow a fast-acting fuse, so the slow-blow design allows the thruster to operate normally while still providing protection against true overloads or short circuits.

The fuse is rated for 80 amps, which is suitable for smaller Sleipner thruster models that fall into that current range. Sleipner specifies these fuses in their installation manuals to ensure safe, reliable operation and to protect cables, motors, switches, and batteries from excessive current.

In practical terms, it’s a simple, rugged, replaceable safety device that sits near the battery and sacrifices itself if something in the system draws more current than it should. When paired with the correct ANL fuse holder, it offers reliable protection in harsh marine environments, resisting vibration, moisture, and the demands of high-current DC systems.
