The MARS 34610 Restring Kit is a field-proven solution for restoring performance to electric furnace and air handler heat strip heaters. Engineered for a 3500W 480V power profile, this kit provides a cost-effective alternative to complete element assembly replacement. Each kit features a high-grade resistance heater coil that is close-wound and designed to be stretched to the required length, ensuring a custom fit across various OEM rack configurations. The welded terminal bolts are a critical technical feature, significantly reducing resistance at connection points to prevent overheating and premature failure. Included in the package are ceramic insulators and terminal bushings (both .375 and .450 inch) to maintain strict dielectric clearance. For safety circuit integrity, a 300 degree fuse link is provided, maintaining the unit's thermal protection standards. This electric heat repair kit is essential for technicians stocking service trucks to handle 480V commercial heating applications where uptime is critical and specific coil geometry varies. Key Benefits for Technicians Universal Stretch-to-Fit Design: Adaptable resistance coil length allows for compatibility with multiple air handler brands and heater rack sizes. Commercial Grade 480V Construction: Specifically rated for 3500W 480V circuits, meeting the high-amperage demands of industrial environments. Reduced Connection Resistance: Integrated welded terminal bolts ensure a secure, low-resistance mechanical connection for long-term reliability. Circuit Safety Components: Includes a 300 degree fuse link and specialized ceramic insulators to restore factory safety specifications. Common Questions Regarding the MARS 34610 How do I determine the correct stretch length for the coil? You should measure the original element's path on the heater rack and stretch the new MARS 34610 coil evenly to match. Avoid over-stretching, as uneven coil spacing can lead to hot spots and secondary failures. Can this 3500W 480V kit be used in 240V systems? No. Using a 480V rated coil in a 240V system will result in approximately 1/4 of the rated wattage, leading to insufficient heating performance. Always match voltage and wattage ratings exactly. What causes original heating elements to fail requiring an electric heat restring? Most failures are due to restricted airflow (dirty filters or blocked coils) or mechanical vibration causing the element to contact the frame. Always check static pressure and fan speeds during the repair. This item is not eligible for free shipping.
