Danfoss 117U4126 Starting Relay HST Compressor Start Relay

The Danfoss 117U4126 is a High Starting Torque (HST) current-sensing starting relay designed for use with refrigeration and air conditioning compressors. This essential component temporarily connects the start winding in the motor circuit, providing the necessary torque required to initiate compressor operation reliably.

Key Features:

• HST (High Starting Torque) design for reliable compressor starting
• Current-sensing relay technology for accurate operation
• Compatible with Danfoss/Secop reciprocating compressors
• Compact, lightweight design for easy installation
• Durable construction for long-term reliability in refrigeration applications

This starting relay is engineered to work seamlessly with refrigerators, freezers, beverage coolers, and other commercial refrigeration equipment. The HST design ensures proper startup even under challenging conditions, while the current-sensing mechanism automatically disconnects the start winding once the compressor reaches operating speed. Suitable for use in various refrigeration systems including walk-in coolers, display cases, and food service equipment.
