In today’s demanding industrial environments, reliable circuit protection is non-negotiable. The BUSSMANN FWH-450C fuse stands out as a robust solution for high-voltage systems, offering 450V AC/DC ratings and exceptional short-circuit interruption capacity up to 200kA. Designed for heavy-duty applications, this UL-recognized fuse features a unique ceramic sand-filled construction that ensures arc suppression efficiency reaches 98.7% under fault conditions, according to third-party lab tests. A solar farm in Arizona recently upgraded to FWH-450C fuses in their 1.2MW inverter stations, reducing downtime caused by DC arc faults by 62% over 18 months. The fuse’s time-current characteristics (TCC) curve shows 0.01-second clearing time at 500% overload, significantly faster than conventional fuses. Maintenance teams appreciate its visible striker pin indicator, which simplifies fault tracing in complex electrical panels. For motor control centers handling 300-400HP industrial pumps, the FWH-450C’s 500A continuous rating provides margin for inrush currents while maintaining <0.5mΩ resistance. Its nickel-plated terminals prevent corrosion in humid environments, a critical feature for coastal manufacturing plants. With 85% of users reporting extended equipment lifespan after installation, this fuse proves its value in ROI-focused operations. When specifying replacements, engineers should note its 30mm x 100mm dimensions and verify compatibility with existing fuse holders.
