Mars 19164 Potential Relay with Quick Connect Terminals

The Mars 19164 is an economy-grade potential relay designed for use in refrigeration and air conditioning compressor applications. This relay provides reliable motor starting control by monitoring back EMF (electromotive force) generated by the compressor motor during startup.

Key Features:

• Quick connect terminal design for fast, secure electrical connections
• Economy construction provides cost-effective performance for standard HVAC applications
• Monitors compressor motor voltage to control start winding circuit
• Suitable for single-phase compressor motors in residential and light commercial systems
• Direct replacement for compatible potential relay applications

Potential relays are essential components in compressor starting circuits, automatically disconnecting the start winding once the motor reaches operating speed. This relay is designed to provide dependable performance in air conditioning, refrigeration, and heat pump systems.
