Mars 16036 Potential Relay 3ARR3J3L3 Refrigeration Start Component

The Mars 16036 is a refrigeration potential relay designed to control the start circuit in single-phase compressor motors. This relay uses back-EMF (electromotive force) sensing to disconnect the start winding once the motor reaches approximately 75% of running speed, ensuring reliable motor starting and protecting the start capacitor from extended energization.

Key Specifications:

• Model designation: 3ARR3J3L3
• Continuous coil voltage rating for reliable operation
• Designed for single-phase compressor applications
• Pick-up and drop-out voltage optimized for refrigeration systems
• Standard terminal configuration for easy installation

Features and Benefits:

• Precision-engineered contacts ensure consistent start circuit operation
• Compact design fits standard control panel installations
• Helps prevent compressor motor damage from start winding burnout
• Compatible with air conditioning and refrigeration systems
• Factory-calibrated for optimal switching performance

Potential relays are critical components in HVAC/R systems, working in conjunction with start capacitors to provide the additional torque needed during compressor startup. The Mars 16036 is built to withstand the demanding cycling requirements of commercial and residential refrigeration applications.
