Frequently Asked Questions
What are glass tube fuses used for on ships?
Glass tube fuses are used to protect electrical circuits in navigation, control, and communication systems from overcurrent, helping to prevent damage and fires.
What sizes of marine glass tube fuses are available?
Common sizes are 5×20mm and 6×32mm, with various current ratings to match your vessel's electrical requirements.
How do I choose between fast-acting and time-delay fuses?
Fast-acting fuses protect sensitive electronics, while time-delay fuses are better for inductive loads like motors that have a high start-up current.
Can I use an automotive glass fuse on my boat?
Automotive fuses may work, but marine-rated fuses are specifically designed to withstand humidity and corrosion. We recommend using marine-grade fuses for safety and reliability.
