Danfoss HST Starting Relay for Refrigeration Compressors

The Danfoss HST starting relay is a current-type compressor start relay for hermetic refrigeration compressors. It is also called a compressor start relay, current relay or refrigerator starting relay. It works with motors that use a high starting torque (HST) motor protector. It switches the compressor's start winding in and out so the compressor starts and runs reliably in refrigerators, freezers and other light commercial refrigeration equipment.

Key Features:

• Current relay design that engages the start circuit at motor inrush and drops it out once the motor is running
• Made for compressors with an HST motor protector
• Available in several pickup and dropout current ratings to match different compressor ranges
• Compact, lightweight assembly that plugs onto the compressor terminals
• Made by Danfoss, a leading name in refrigeration compressors and components

A failed or worn start relay is a common reason a compressor will not start or keeps cycling on overload. Replacing it with a Danfoss relay restores dependable starting. Choose the child item whose current rating and compressor range match your application.
