Import Bussmann High Speed Fuse Fwj-150a — Buy in wholesale FOB from Supplier in China

The Bussmann FWJ-150A is a North American style high speed fuse designed for DC and AC protection, rated at 150 A with a voltage capacity of 1000 Vac or 800 Vdc. It features bolted tags for secure mounting and is engineered to safeguard DC common bus systems, DC drives, power converters, rectifiers, reduced rated voltage starters and high voltage traction inverters. The fuse has an interrupting rating of 25 kA RMS symmetrical for currents between 35-200 A, scaling up to 100 kA RMS symmetrical for 250-2000 A, and 50 kA at 800 Vdc for select current ranges.

Constructed to meet UL Recognized standards (JFHR8, E91958 for 50-600 A) and CE certification, the FWJ series uses materials and design principles typical of high speed fuses, ensuring rapid response to overcurrent conditions to prevent damage to downstream equipment. The fuse body is typically made from high-grade ceramic or composite materials, with internal elements calibrated for precise melting characteristics under fault conditions. Industry standard tolerances for such fuses include tight control over melting time-current curves to ensure consistent performance.

These fuses are commonly used in industrial power systems, renewable energy installations and railway traction applications where reliable overcurrent protection is critical. Buyers typically include OEMs of power electronics, system integrators and maintenance teams for heavy machinery. The FWJ-150A is part of a broader range spanning 35 to 2000 A, allowing for scalable protection across different power levels.
