Overview

The Littelfuse SPXV Series In-Line Solar Fuse (SKU: SPXV001) is engineered to provide robust and reliable overcurrent protection for demanding photovoltaic (PV) systems. Designed to meet the stringent requirements of modern solar installations, this fuse plays a critical role in ensuring the safety, efficiency, and longevity of solar power generation infrastructure. With a substantial 1500 VDC voltage rating and available in a wide range of amperage ratings from 1A to 60A, the SPXV series offers unparalleled flexibility for diverse solar applications. This fuse series is specifically developed to protect solar strings, inverters, and combiner boxes from damaging overloads and short circuits. Its full-range, fast-acting design effectively mitigates common low-overload faults, preventing potential system failures and costly downtime. The SPXV fuses boast impressive interrupting ratings, with up to 30 kA for lower amperage models (1-20A) and a robust 50 kA for higher amperage models (35-60A) and the SPXV-M 25-32A variants. This high interrupting capacity ensures that the fuse can safely clear fault currents, protecting sensitive equipment downstream. Key features and benefits of the Littelfuse SPXV Series include: * **High Voltage Rating:** 1500 VDC, suitable for high-voltage solar arrays and systems. * **Wide Amperage Range:** Available from 1A to 60A, allowing for precise application matching. * **High Interrupting Rating:** Up to 50 kA, providing superior fault current protection. * **Fast-Acting Design:** Helps to quickly isolate faults and prevent damage. * **Compact Design:** Offers higher amperage protection in less space, enhancing design flexibility. * **Durable Construction:** Melamine body and nickel-plated copper alloy caps ensure longevity in harsh environmental conditions. * **Approvals:** UL 248-19 Listed (File: E339112) and compliant with UL 248-1, 248-19, and IEC 60269-6 standards. * **Environmental Compliance:** RoHS Compliant and REACH certified. The SPXV Series is an integral component in safeguarding solar power systems. Its applications extend to critical areas such as inverters, where it protects against internal faults and external surges, and combiner boxes, where it provides individual string protection. The fuse's construction utilizes high-quality melamine for the body and nickel-plated copper alloy for the caps, ensuring excellent conductivity and resistance to corrosion, even in challenging outdoor environments. Manufactured in Mexico, these fuses uphold Littelfuse's commitment to quality and reliability. For installers and system designers, the SPXV Series offers peace of mind. The availability of different fuse sizes (10 x 85 mm for 1-32A and 20 x 127 mm for 35-60A) and the option for specialized part number configurations (e.g., SPXVxxxT, SPXVxxxL, SPXVxxx-XM) provide further customization. Littelfuse, a globally recognized leader in circuit protection, has developed the SPXV Series to address the evolving needs of the renewable energy sector, ensuring that solar power systems operate safely and efficiently for years to come. Recommended accessories like fuse holders (LFPXV001) and fuse blocks (LFXV15060-BC) are also available to facilitate seamless integration into existing or new solar infrastructure.
