Gould Shawmut Amp-Trap Semiconductor Fuse A60X600-4

The Gould Shawmut Amp-Trap A60X600-4 is a high-performance, fast-acting semiconductor fuse designed for protecting sensitive electronic components such as diodes, thyristors, and power semiconductors from overcurrent and short-circuit conditions. Manufactured by Gould Shawmut (now part of Mersen), this fuse features a Form 101 design with blade terminals for easy installation in fuse holders or blocks. It offers superior current-limiting capabilities, minimizing damage to equipment by interrupting faults quickly and efficiently. Key applications include industrial power supplies, motor drives, UPS systems, and renewable energy inverters where reliable protection against high fault currents is critical. Advantages over similar products include high interrupting ratings up to 100kA, low I²t values for better semiconductor protection, and compliance with UL and CSA standards. Drawbacks may include higher cost compared to general-purpose fuses and the need for precise matching to system voltage and current ratings. This model is rated for 600V AC and 600A, making it suitable for medium-voltage applications. Based on the provided images, the fuses appear to be in new condition, with intact labels and no visible wear, likely new old stock.
