ETI holder NH3 630A/1000Vdc

Fuse Size (NH Size) • NH 0: This is the smallest size in this series of NH fuse holders. It is typically used for lower current fuses. Typical for smaller installations where less current is required. • NH 1: This is a mid size fuse holder, used for fuses that can pass a higher current than NH 0. • NH 3: This is a larger fuse holder, designed for the highest rating in this series. It is typically used in heavier industrial installations where high currents are required. Current and Voltage Specifications • NH 0: Suitable for fuses up to approximately 160A (amperes) 1000 volts max, depending on the exact application and installation. • NH 1: Can handle fuses up to approximately 250A (amperes) 1000 volts max • NH 3: Designed for heavy duty fuses and can handle currents up to 630A at (amperes) 1000 volts max, which is necessary for large industrial applications where high power needs to pass through. • Please note that the maximum voltage and current are determined by the fuse specifications! 1P, 2P and M8 or M10 meaning • 1P is a single version • 2P is a double version (2 fuse holders connected next to each other) • M8/M10 indicates which size bolt connections are used. Physical dimensions • The physical dimensions of the fuses and the holder itself differ per type. An NH 0 fuse is smaller than an NH 1 or NH 3 fuse. This means that the NH 0 holders are more compact and take up less space in the installation cabinet, while NH 3 holders are larger and more robust to allow more current to pass. Areas of application • NH 0 is often used in smaller systems, such as residential or light commercial applications. • NH 1 is used in medium-sized industrial installations. • NH 3 is intended for heavy-duty applications where high power is required, such as power plants or large industrial plants.
