When you're dealing with a failing element in an electric furnace or air handler, the MARS 34604 Restring Kit provides a field-ready solution for restoring 5000W 480V heating capacity without replacing the entire heater assembly. This kit is engineered for commercial and industrial HVAC electric heater repair, featuring a high-grade Nichrome resistance heater coil. The 3/8-inch diameter coil is close-wound and designed to be stretched to length, allowing for precise fitment across various strip heater and duct heater configurations. For long-term reliability, the coil utilizes welded terminal bolts that minimize resistance at connection points, preventing common hot-spot failures. Each MARS 34604 kit is a comprehensive heating element replacement package, including ceramic insulators, bushings, and a 300-degree fuse link to ensure the system meets safety specifications after the refresh. Integrating this 480V restring kit into your maintenance routine reduces equipment downtime and maintains the energy efficiency of the heating bank. Key Benefits: Optimized Performance: Delivers a consistent 5000W at 480V, specifically tailored for high-voltage commercial air handlers and furnaces. Durable Construction: Heavy-duty Nichrome coil with welded terminals ensures low-resistance electrical paths and structural integrity over repeated thermal cycles. Universal Versatility: The stretch-to-fit design makes this electric furnace restring kit compatible with multiple OEM mechanical footprints. Complete Installation Hardware: Comes equipped with male and female ceramic insulators, standard and extra-long bushings, and necessary terminal hardware for a professional finish. Common Questions: Can this kit be used in 208V or 240V systems? No, the MARS 34604 is specifically rated for 480V applications. Using a 480V coil on lower voltage systems will result in significantly reduced wattage output and poor heating performance. What is the maximum stretch length for this coil? The Nichrome coil is designed to be stretched from approximately 61 inches up to 176 inches, providing ample range for most industrial strip heater replacements. Does the kit include overheat protection? Yes, the assembly includes a 300°F fuse link, which is a critical safety component for preventing thermal runaway in the event of airflow failure.
