Description

Designed for robust industrial and commercial applications, this UL North American product offers reliable performance with a focus on safety and efficiency. The unit is rated to handle a current of 175 A, making it suitable for demanding electrical systems that require consistent power management. Operating at a rated voltage of 600/300 VAC/VDC, it provides versatility in various settings, accommodating both alternating current (AC) and direct current (DC) environments. Weighing in at just 0.754 lb, the product combines lightweight design with durable construction. Its compact body size measures 1.62 inches in diameter and extends to a length of 5.75 inches, ensuring ease of installation even in space-constrained setups. The mounting type is clip-based, facilitating straightforward attachment without compromising stability or reliability. One of the standout features is its impressive breaking capacity of 200 kA, which ensures effective interruption under fault conditions—critical for maintaining system integrity and preventing damage during overcurrent events. This high breaking capacity aligns seamlessly with its classification as a Class J fuse. The terminal type is blade-style, optimized for secure connections while minimizing resistance losses across junctions. Both the body material and insulation are crafted from GMG (Glass-Melamine-Glass), known for excellent thermal stability and electrical insulation properties—ideal for high-performance applications requiring enduring material strength. For connection terminals, brass alloy is employed due to its superior conductivity and corrosion resistance characteristics—ensuring long-term reliability even in challenging operational environments. Rated for operation within the standard frequency range of 50/60 Hz, this product caters to both domestic and international markets where these frequencies are prevalent. In summary, this UL North American device combines essential attributes such as high current rating capability, versatile voltage compatibility, robust breaking capacity, and durable materials—all packaged into a user-friendly form factor designed for efficient integration into existing systems. Whether you're upgrading an industrial setup or ensuring compliance with stringent safety standards in commercial installations, this product delivers dependable performance tailored to your technical requirements.
