The 3PIN Terminals Refrigerator PTC Starter Relay with 12 Ohm Resistance is a PTCbased starting device designed for refrigerator compressors. It provides a controlled starting current through the compressor start winding and then automatically limits current after the motor begins to run, helping to protect the compressor and improve reliability. Key benefits Reliable compressor start: Delivers a precise starting current to initiate motor startup and reduce the chance of failed starts. Selfregulating PTC technology: Uses a positive temperature coefficient thermistor to automatically increase resistance after startup, minimizing wear on the start circuit. Easy installation with 3pin terminals: The threepin configuration simplifies wiring and compatibility with many standard refrigerator compressor setups. Clear specification: 12 ohm resistance is specified for startup characteristics, helping match with compatible compressors. Durable and compact design: Built as a practical replacement part that fits standard startrelay applications without adding bulk to the appliance. Key attributes Functionality: 3PIN Refrigerator PTC Starter Relay to provide starting current to a compressor and then disengage as the run winding takes over. Compatibility: Designed for refrigerator compressors that use a 3pin terminal configuration in their starter circuit. Size/Form factor: Compact starter relay suitable for standard mounting and wiring installations in common refrigerator assemblies. Material/Build: Constructed as a practical PTC start device with a fixed resistance specification of 12 ohms. Performance: Delivers reliable starting performance with automatic current reduction after the compressor starts, supporting stable operation. What this product does Acts as a starter relay for refrigerator compressors, enabling a smooth and reliable start sequence. Uses PTC thermistor characteristics to limit current once starting is complete, helping to protect the start circuit. Provides a straightforward replacement option for units with 3pin terminal start configurations. Applications and use cases Household refrigerator maintenance: a failed or worn starter relay in a refrigerator that uses a 3pin compressor connection to restore reliable startup performance. Refrigerator and service: A practical spare part for technicians servicing appliances with 3pin start circuits, enabling quick field replacements. Replacement for legacy or damaged PTC starters: Suitable as a direct substitute when a 3pin PTC starter relay is required, restoring normal compressor startup in compatible units. Notes for installation and fit Ensure compatibility with your refrigerator's compressor 3pin terminal configuration before installation. Confirm that the startup resistance specification of 12 ohms aligns with the compressor model requirements to achieve proper startup performance. Follow standard electrical safety practices and appliance service guidelines when replacing the relay. This description maintains a professional and clear tone, presenting the product's purpose, benefits, and specifications without embellishment, while aligning with the stated features: a 3PIN terminals refrigerator PTC starter relay with 12 ohm resistance.
