Product catalog summary
Overview: Italweber's ultra-quick NH fuses are designed for semiconductor protection, featuring high breaking capacity and low specific let-through energy.
Specifications: These fuses have a steatite body for thermal and mechanical resistance, a silver-plated copper fuse element, and quartz sand for arc extinguishing. They meet standards CEI 32-1, CEI 32-7, IEC EN 60269-1, IEC EN 60269-4, and DIN 43653.
Product Series: The document describes several series, including NHL, T/80, TN/80, E/80, A-69E, and A-125E, each with specific applications. The NHL series ranges from sizes 00 to 3, with current ratings from 16A to 630A and a voltage rating of 690V. The A-125E series supports voltage ratings up to 1250V.
Mounting and Accessories: Fuses are designed for screw-fixing with 80 mm or 110 mm mounting distances. Optional microswitches can be added for remote operation indication. Single-pole fuse bases are available for various mounting distances.
Ordering Information: Detailed tables provide order codes, sizes, current and voltage ratings, and packaging configurations for each series. Microswitch order codes are also included.
