UL-Class Fuses for the North American Market One of Vicfuse’s greatest strengths is its range of UL-Class low-voltage fuses, designed especially for compliance with American standards. In the U.S. electrical market, Underwriters Laboratories (UL) defines distinct classes of fuses — including Class CC, T, J, G, L, RK1/RK5, H, and others. Each class has standardized dimensions and performance criteria to ensure interchangeability and adequate protection in UL-listed electrical panels. Vicfuse supplies all the major UL fuse classes, giving North American OEMs and panel builders a one-stop source for their circuit protection needs. For example, Vicfuse’s Class CC fuses (like the VCT series) are 600V, time-delay branch-circuit fuses rated up to 30A, ideal for protecting small motors, lighting, and control circuits. At the other end of the spectrum, Vicfuse produces high-capacity Class L fuses (such as the VLT series) rated up to 6000A for heavy industrial mains protection. In between, the company covers Class T fuses for compact, fast-acting protection of feeder circuits, Class J fuses (600V, up to 600A) for space-saving panel protection, and Class G fuses for lighting and appliance circuits. All these fuses are engineered to meet the UL 248 standards for their class and carry the requisite UL markings. In fact, Vicfuse designs its products in accordance with UL specifications — for instance, the VTF Class T fuse is explicitly “designed according to UL248–15” and fully compliant with UL safety requirements. By offering such a complete lineup of UL-listed fuses, Vicfuse empowers equipment manufacturers and installers in North America to meet National Electrical Code (NEC) protection standards with confidence. Whether it’s a Class CC fuse for a control panel or a Class L fuse for a large switchboard, Vicfuse delivers a certified solution that can drop right into UL-listed fuse holders and disconnect switches.

Comprehensive Product Range for Every Need Beyond UL-class fuses, Vicfuse boasts a comprehensive product portfolio covering nearly every circuit protection category. This breadth is one of the company’s key advantages — clients can source everything from miniature electronic fuses to high-voltage industrial fuses from a single reliable manufacturer. Vicfuse’s offerings include:

• Semiconductor Protection Fuses (High-Speed Fuses): Fast-acting fuses (aR/gR type) designed to safeguard power semiconductors like diodes, thyristors, inverters and UPS systems. These fuses, such as the VR series, feature ultra-low I²t to protect sensitive devices and are rated for various voltages (e.g. 150V, 300V, 600V, up to 1000V or more). They are UL recognized and widely used in renewable energy and industrial drives where fault currents must be cut off in microseconds.
• DC Fuses and High-Voltage Fuses: Specially engineered fuses for direct current applications, including battery storage systems and DC power conversion. Vicfuse’s VD series, for example, is a 1200V DC fuse line with ratings from 20A to 1800A, offering a high interrupting capacity (100kA) to protect critical DC circuits. The company also produces medium and high voltage fuses for power distribution — including medium-voltage drop-out fuses used by utilities and HV fuses for equipment up to several kV. These products cater to the electric power industry’s needs for safe grid operation.
• General Purpose Low-Voltage Fuses: Besides the UL-class fuses discussed, Vicfuse offers IEC and BS standard fuses, midget fuses (10x38mm), D/D0 neo fuses, and more for global markets. This means customers worldwide — whether following IEC standards in Europe or JIS/BS standards elsewhere — can find suitable Vicfuse equivalents. The fuses come in fast-acting or time-delay versions to cover general circuit protection in industrial, commercial, and residential settings.
• Special Purpose Fuses: Vicfuse stays ahead of industry trends by supplying fuses tailored for emerging applications. Key examples include EV/HEV protection fuses for electric vehicles, solar PV fuses for photovoltaic arrays, telecommunications fuses for telecom power systems, and battery protection fuses for energy storage systems. These fuses are built to handle unique stresses — e.g. EV fuses can safely interrupt high DC voltages in milliseconds to protect battery packs, and PV fuses are rated for 1000VDC or higher to guard solar panel strings. As the world moves toward e-mobility and renewable energy, Vicfuse’s special-purpose lines ensure that protection technology keeps up. Notably, the surge in electric vehicle adoption is driving huge demand for fuses — modern EVs use 50% more fusing points than traditional cars, with premium models requiring nearly 200 fuses per vehicle. Likewise, the expansion of solar farms and wind power (up ~40% since 2020) necessitates thousands of robust DC fuses for safety, which Vicfuse provides through its PV fuse series.
• Fuse Accessories and Power Distribution Components: To complement its fuse selection, Vicfuse also manufactures high-quality fuse holders, fuse bases, and power distribution blocks for safe installation of fuses in electrical systems.
