Rated at 250A, the Blue Sea Systems 5118 is a Class T fuse for use in compatible Class T fuse blocks. Its fast short-circuit response helps interrupt severe fault currents quickly, while the 20,000A interrupt capacity supports large battery and inverter systems. The fuse is UL listed to standard 248-15 and DC tested to UL standard 198L.
- 250A Class T rating: Provides overcurrent protection for high-capacity DC circuits.
- Extremely fast short-circuit response: Helps interrupt fault currents quickly to protect connected wiring and equipment.
- 20,000A interrupt capacity: Handles high available fault currents in large battery and inverter installations.
- UL listed to standard 248-15: Supports use in installations requiring this recognized fuse standard.
- DC tested to UL standard 198L: Provides verified testing for DC fuse applications.
- Compatible fuse-block use: Installs in a suitable Class T fuse block for marine, RV, automotive, and other DC systems.
The Blue Sea Systems 5118 is intended for high-current DC protection where a fast-acting Class T fuse is required. It can be used in marine electrical systems, RV power distribution, automotive installations, inverter circuits, and large battery banks when matched with a compatible fuse block and correctly sized conductors.
When a short circuit occurs, the fuse is designed to respond rapidly and open the circuit, limiting the flow of fault current. Its 20,000A interrupt capacity supports systems with substantial available fault current, including high-capacity battery and inverter setups. Confirm the fuse-block rating, system voltage, cable sizing, and circuit requirements before installation.
The compact fuse measures approximately 2 inches high by 4 inches wide by 6 inches long as packaged and weighs about 0.3 lb. A California Proposition 65 warning applies to this product.
