Description
ZAF5 Start Relay for Domestic Refrigerators (Compressor Group)
The ZAF5 series start (start-protection) relay is designed to start and protect single-phase asynchronous compressor motors in domestic refrigerators and freezers. The relay provides a short-term power supply to the compressor's start winding at the moment of ignition and protects the motor from current overloads and overheating during emergency operating modes.
Key Advantages and Features:
- Stable Compressor Start: The built-in PTC (Positive Temperature Coefficient) element ensures precise and reliable switching of the start winding.
- Overheat and Overload Protection: Prevents motor winding burnout in case of rotor jamming, voltage drops, or frequent starts.
- Heat-Resistant Housing: Made of durable non-conductive plastic, resistant to high temperatures and constant vibrations.
- Easy Replacement: The standard contact group allows for quick installation of the part to replace a failed original relay.
