Fuse NT00 125A

Description

The NT00 125A HRC Blade Ceramic Fuse Link (frequently cross-referenced with the NH00, RT16-00, or RO30 series) is an industrial-grade, high-breaking-capacity (HRC) electrical safety device. Enclosed in a high-density, thermal-shock-resistant ceramic body and packed with quartz sand, this knife-blade fuse is specifically engineered to provide robust short-circuit and overcurrent protection for demanding low-voltage electrical systems. When an electrical fault or current spike exceeding 125A occurs, the internal pure copper fuse element safely melts, extinguishing the resulting electrical arc within the sand matrix to instantly isolate the downstream circuit and protect high-value machinery. Key Features & Specifications Model Type: NT00 / NH00 / RT16-00 Current Rating: 125A (Amperes) Voltage Ratings: AC 500V (commonly used up to 660V/690V) | Select variants rated for up to 60V–250V DC applications Breaking Capacity: High breaking threshold up to 120kA Operating Characteristic: gG/gL (General purpose full-range breaking capacity for cables and conductors) Material Build: High-grade ceramic/porcelain square pipe housing with corrosion-resistant silver-plated copper knife-blade contacts. Indicator: Features a top-mounted visual trip indicator mechanical tab to immediately identify a blown fuse. Compatible Equipment & Systems The NT00 125A blade fuse is a standardized industrial component compliant with IEC 60269 standards. It is natively compatible with a wide array of electrical distribution systems, heavy machinery, and renewable energy setups: 1. Compatible Fuse Bases & Holders Fits all standard Size 00 (NT00 / NH00) Ceramic or Plastic Fuse Bases equipped with spring-loaded knife contacts. Seamlessly slides into KETO-00 and other NH00-compatible manual three-pole or single-pole strip fuse switch disconnectors. 2. Renewable Energy & Battery Isolation Systems Solar Inverter Off-Grid Systems: Widely utilized in DC solar combiner boxes and low-voltage battery storage systems (e.g., 24V or 48V Lithium/Lead-Acid battery banks) to protect high-capacity power inverters. Compatible with battery disconnect enclosures from brands like Victron Energy, Jean Müller, and MCE. 3. Industrial Electrical Panels Main Distribution Boards (MDBs): Installed inside commercial and industrial electrical panels to shield main sub-circuits. Motor Control Centers (MCCs): Acts as backup overcurrent protection for large industrial electric motors, ventilation fans, and heavy pumping machinery. 💡 Safety & Fitment Check Tip: The NT00/NH00 size is the most compact of the standard knife-blade industrial fuses. Before replacing, ensure your existing holder is configured for Size 00 spacing. Always use an insulated NH Fuse Puller (Extractor Handle) to safely remove or insert these live blade links under load maintenance environments.
