Danfoss 7701021 Start Kit
The Danfoss 7701021 Start Kit is a crucial technical component for field technicians working with single-phase CSR (Capacitor Start Run) compressor configurations. Engineered for high-starting torque applications, this kit provides the vital electrical boost necessary to overcome initial inertia in Danfoss MTZ and NTZ reciprocating compressors, specifically within the 018-048 range. The CSR starting kit integrates a high-voltage start capacitor with a rated capacitance of 100 MFD, alongside precise run capacitors of 10 µF and 15 µF, ensuring stable motor operation and optimal power factor correction during the climb to running speed.
For contractors servicing refrigeration and HVAC systems, the 7701021 is the reliable choice for ensuring compressor motor starting efficiency in 208-240V environments. By providing a high-starting torque (HST) profile, it reduces mechanical stress on the internal windings and prevents common startup failures in low-voltage scenarios. This OEM Danfoss part is purpose-built to maintain the electrical integrity of hermetic systems, offering a 10+15+100MFD total capacitance balance that meets strict UL and CE technical standards for commercial and light industrial applications.
Key Benefits for Technicians- Optimized Starting Torque: Provides the necessary spike in current to launch Danfoss MT/Z 018-1 through NTZ 048-1 compressors under heavy load.
- Robust CSR Logic: Utilizes 10+15+100 MFD capacitance to balance phases, minimizing internal heat during the transition from start to run cycles.
- Enhanced System Resilience: Drastically reduces the risk of "stuck" compressors and motor burnouts by ensuring high-speed acceleration.
- Certified Engineering: Fully UL and CE approved for compatibility with standard 208-240V single-phase commercial refrigeration circuits.
- Drop-in Compatibility: Compact footprint (2.668 Liter volume) designed for seamless integration into existing HVAC electrical cabinets.
- What compressors are compatible with the 7701021 kit? This kit is specifically calibrated for Danfoss reciprocating compressors, including the MTZ18, MTZ22, MTZ28, MTZ32, MTZ36, MTZ44, and NTZ series operating on single-phase voltage.
- When should I replace a start kit versus just the capacitor? If you observe repeated compressor trip-outs or humming without ignition, the 7701021 CSR kit provides a comprehensive solution for aging electrical components beyond a single failed capacitor.
- Can this be used for 208V to 240V conversions? Yes, it is rated for 208-240VAC applications, making it ideal for standard 3-wire grounded systems in commercial or residential settings.
