Eaton FWX-300A Bussmann FWX high speed fuse 300A (Stud mount blade end x blade end) FWX300A

Product Description

Eaton FWX-300A is a Bussmann series high-speed fuse rated 300 A RMS and 600 V for fast interruption of fault currents. The non-indicating cartridge fuse uses blade end to blade end terminations with stud mounting and provides high interrupting capacity for AC and DC systems. Typical attributes include low watt losses and specific I2T clearing values for semiconductor and power converter protection.

• Rated 300 A RMS, 600 V with 200 kAIC AC and 50 kAIC at 250 Vdc interrupting ratings
• Blade end x blade end termination, stud mount, cartridge body, ceramic construction
• Typical watt losses 32 W; clearing I2T 27300 at 250 V, pre-arc I2T 6000; applications include DC common bus, DC drives and power converters

Product Highlights

High-speed 300 A, 600 V cartridge fuse with blade end terminations, stud mount, 200 kAIC AC interrupting capacity, non-indicating design.
