Description

When it comes to selecting reliable components for electrical systems, understanding the specifications is crucial. This UL North American rated product offers a robust solution for industrial and commercial applications with its impressive technical features. With a rated current of 900 A, this component is designed to handle substantial electrical loads, making it suitable for demanding environments. Its versatility in handling both AC and DC voltages—up to 600 VAC or 500 VDC—ensures broad applicability across various systems. The physical dimensions of this product include a body size of 2.5 inches in diameter and a length of 10.75 inches, translating to approximately 63 mm by 273 mm. The compact design does not compromise on performance; instead, it provides an efficient use of space within your setup. Weighing in at just 4.29 lb (approximately 1.95 kg), it's relatively lightweight for easy installation without sacrificing durability. Designed as a bolt-in mounting type with blade terminals made from silver-plated copper, this product guarantees excellent conductivity and ease of connection while minimizing resistance losses. The GMG body material ensures robustness against environmental stresses while offering effective insulation properties due to the same GMG insulation material. A notable feature is its high breaking capacity of up to 200 kA, which means it can safely interrupt fault currents without damage or risk to connected equipment—a critical factor when considering safety and reliability in power distribution networks. Operating efficiently across frequencies ranging from 50 Hz to 60 Hz further emphasizes its adaptability in different regions or applications where frequency variations might be encountered. Class L fuses are known for their time-delay characteristics that allow temporary overloads without tripping unnecessarily—a beneficial trait for systems experiencing transient surges during startup phases or variable load conditions. In summary, this component stands out with its combination of high current rating, versatile voltage support, compact yet sturdy construction, excellent material choices for connectivity and insulation—all wrapped up with significant safety assurances through its high breaking capacity and Class L fuse classification. These attributes make it an ideal choice for professionals seeking dependable performance under challenging conditions while maintaining operational flexibility across diverse settings.
