Nibe 718218 Soft Start Module – 3×230V (Three-Phase)

The Nibe 718218 Soft Start Module is a purpose-built component designed for three-phase 230V Nibe heat pumps. This unit replaces the older blue resistor PCB, offering improved motor protection and start-up performance by gradually increasing voltage to the compressor, thereby reducing inrush current and mechanical strain.

Technical Specifications:

• Nibe Part Number: 718218

• Type: Soft Start Module

• Voltage: 3×230V AC (Three-phase)

• Function: Limits start-up current for compressor motors

• Replaces: Legacy blue resistor PCB

• Installation: Internal cabinet mounting with dedicated wiring points

Compatible Nibe Models:

• Nibe F1145 - 3 phase only

• Nibe F1245 - 3 phase only

• Nibe F1330 – all kW variants

• Nibe F2025 - all kW variants

• Nibe F2300 -  all KW variants

This soft start module is essential for compressor protection in three-phase low voltage installations where direct-on-line start-up could lead to fuse blowing, mechanical stress, or power supply interruptions.

Features & Benefits:

• Smooth voltage ramp-up for safe compressor start

• Replaces outdated resistor-based soft start boards

• Helps reduce electrical nuisance tripping

• Increases system durability and start-up reliability

• Recommended for both new installs and retrofit upgrades in compatible models
