ETI Holder NH3 630A/1000VDC Tweepolig

Fuse size (NH size) • NH 0: This is the smallest size in this range of NH fuse holders. It is typically used for lower amperage fuses. Typical for smaller installations where less power is required. • NH 1: This is a medium sized fuse holder, used for fuses that can carry a higher current than NH 0. • NH 3: This is a larger fuse holder, designed for the highest rating in this range. This is usually used in heavier industrial installations where high currents are required. Current and Voltage Specifications • NH 0: Suitable for fuses up to approximately 160A (ampere) 1000 volts max, depending on the exact application and installation. • NH 1: Can handle fuses with a current of up to approximately 250A (ampere) 1000 volts max • NH 3: Designed for heavy-duty fuses and can handle currents up to 630A (ampere) 1000 volts max, which is necessary for large industrial applications where high power have to go through. • Please note that the maximum voltage and current is 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 linked 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 vary by type. An NH 0 fuse is smaller than an NH 1 or NH 3 fuse. This means that 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 through. Areas of application • NH 0 is often used in smaller systems, such as in residential or light commercial applications. • NH 1 is used in medium-sized industrial installations. • NH 3 is intended for heavy-duty applications where a lot of power is required, such as in power stations or large industrial factories.
