⚡ Nibe 518736 Soft Start – 3×400V (Three-Phase)

The Nibe 518736 Soft Start Module (V60HM) is a robust electronic control unit designed to reduce start-up current surge in three-phase Nibe heat pump systems. By gradually ramping up motor voltage at startup, it protects both the compressor and the electrical infrastructure, enhancing system reliability and longevity.

🔧 Technical Specifications:

• Nibe Part Number: 518736

• Type: Soft Start Module

• Voltage: 3×400V AC (Three-phase)

• Function: Reduces inrush current on compressor startup

• Model Code: V60HM

• Mounting: Internal cabinet or designated control housing

• Phases Supported: 3-phase motor systems only

✅ Compatible Nibe Units:

• Nibe F1345 – all kW variants

• Nibe F1145 – all kW variants

Typically installed in larger ground source heat pumps where high power draw at startup needs to be mitigated to prevent nuisance tripping or overloads on supply fuses.

🛠️ Key Benefits:

• Reduces electrical stress on the compressor and components

• Minimizes fuse trips and grid disturbances during startup

• Helps meet electrical compliance standards for installations with limited grid tolerance

• Enhances overall lifespan of the heat pump's mechanical and electrical systems
