Blue Sea Systems Class T Fuse 150A – BSS-5114
Provide reliable high-current protection for your vessel’s main DC circuits with this 150A Class T fuse from Blue Sea Systems. Class T fuses are the industry standard for protecting large-draw marine systems — including battery banks, inverters, windlasses, and bow thrusters — where a conventional blade or AGC fuse simply isn’t rated for the job. Their fast-blow characteristics and high interrupt rating make them the right choice wherever a fault could otherwise cause serious damage to wiring or equipment.
The BSS-5114 is a single 150A fuse designed for use with a compatible Class T fuse block or holder, providing a clean, serviceable main protection point in your DC distribution system.
Key Features
- 150A rating — suitable for high-current marine DC main circuits
- Class T fast-blow design with high interrupt rating
- Protects battery banks, inverters, windlasses, and bow thrusters
- Requires a compatible Class T fuse block or holder
- Manufacturer Part Number: BSS-5114
Parts Desk Insights
Best Use Case: The BSS-5114 150A Class T fuse is best suited as the main overcurrent protection device between your battery bank and primary DC distribution bus — particularly on vessels with inverters, electric windlasses, or bow thrusters drawing sustained high current. If your system requires a higher rating, step up to the 250A Class T Fuse (BSS-5118) or the 400A Class T Fuse (BSS-5121) for larger battery banks and high-capacity inverter installations.
