Brand: Go Power! · SKU: 400-BLEW · MPN: GPO44367 (from one listing) · Category: Components
A 400 Amp Class T slow blow fuse designed specifically for protecting high-power inverters in applications like RVs, boats, or off-grid solar systems. It features a semiconductor design that guarantees complete power termination when blown, preventing damage to expensive inverter equipment. The 'slow blow' characteristic allows it to handle temporary current surges without nuisance blowing, while still providing critical overcurrent protection against sustained overloads. It is explicitly mentioned as a direct replacement for the FBL-400 fuse and has a high interrupting capacity.
