Factory Direct: HG2B Vertical Fuse Rail Switch Disconnector For Efficient Power Distribution

Fuse-switch HG2B Disconnector is used below 690V of Rated Voltage. There is a 160A to 630A primary current. In a power system, it is mostly utilized as a power switch, isolator switch, and emergency switch. Assorted fuse links: NH00 for 160A, NH1 for 250A, NH2 for 400A and NH3 for 630A Rated currents: 4, 6, 10, 16, 20, 25, 32, 35, 40, 50, 63, 80, 100, 125, 160, 200, 224, 250, 300, 315, 355, 400, 425, 500 and 630 fuse,fuse switch, Insulating voltage of the HG2B fuse type isolation switch is AC800V. 400V, 690V, and 50HZ are the operating voltage and frequency ratings. This switch is not used to power a single motor; instead, it serves as a power switch, isolating switch, and emergency switch with the function of protecting circuits with high short circuit currents and motor circuits. When an isolator knife replaces a fuse, this switch does not have the ability to overload an electric circuit with short circuits, and instead only meets the rating that it was designed to withstand with the ability to isolate uses when a minute break occurs. This product complies with GB14048.3-2002.IEC 947-3 standards (1999)

Applicable Environment
