Overview

The Littelfuse LFXV150601C is a high-voltage fuse block specifically engineered for demanding photovoltaic (PV) systems, including string and high-capacity combiner boxes. This robust component is designed to securely house 1500 Vdc rated, 20 x 127 mm fuses with current ratings ranging from 35 to 60 amperes. It provides essential overcurrent protection with a significant fault current withstand rating of 50 kA, meeting the stringent requirements of large-scale solar installations. Key features enhance safety, efficiency, and ease of use. The dead-front cover design ensures personnel protection, while the ventilated design promotes cooler operation, extending fuse longevity even under high ambient temperatures and current loads. Its narrower width of 34.79 mm (1.37 in) maximizes panel space, allowing for more blocks within a given area. Maintenance is simplified with a tool-free fuse removal and replacement system, and a positive lock feature secures the fuse puller when the fuse is absent. Installation is streamlined with a 35 mm DIN-rail mounting option for quick assembly. The LFXV150601C offers installation flexibility by accepting both wire and busbar connections. It is constructed from durable thermoplastic with tin-plated copper alloy fuse clips and tin-plated aluminum screws, ensuring excellent conductivity and corrosion resistance. The operating temperature range is -55°C to +125°C, and it meets UL94 V-0 flammability standards. The block is UL 4248-19 Listed (File E345481), and the cover is UL Listed Fuse Accessory (File E184929), ensuring compliance with industry safety standards. It is also RoHS compliant, Lead (Pb) free, and REACH compliant. This fuse block is ideal for pre-combining multiple solar strings in harnesses, reducing the number of inputs into combiner boxes and consequently decreasing installation time and labor costs. Recommended fuses include Littelfuse SPXV 20 x 127 mm fuses rated 35–60 amperes. The SKU is LFXV150601C. Manufactured in Mexico and distributed by Gross Automation.
