Copeland 940-0090-06 Relay

The Copeland 940-0090-06 Relay is a high-performance current relay engineered for precise motor starting control in HVACR compressor applications. Designed as a critical OEM replacement part, this relay features a calibrated 24.75 A pick-up rating and a 20.45 A drop-out rating, ensuring the start circuit is engaged and disengaged at the exact amperage thresholds required to protect the motor windings. As a veteran-grade HVAC control relay, the 940-0090-06 is built to withstand the rapid cycling and thermal stresses common in commercial refrigeration and air conditioning systems. Integrating this relay into your compressor troubleshooting routine ensures stable start-up torque and prevents the high-current lag that leads to premature motor failure. Its robust construction provides reliable switching for single-phase motors, maintaining the electrical integrity of the system without the "marketing fluff" of lower-tier universal components.

• Precise Amperage Calibration: Accurate 24.75A pick-up and 20.45A drop-out ratings provide consistent start-cycle management.
• Enhanced Motor Protection: Prevents start capacitors from remaining in the circuit, reducing the risk of overheating motor windings.
• Industrial Durability: Constructed to meet rigorous Copeland compressor specifications for long-term field reliability.
• Standardized Fit: Designed for seamless integration with existing HVACR electrical systems and mounting brackets.

How do I verify if the 940-0090-06 relay has failed?
Technicians should perform a continuity test across the normally closed contacts and check for pitted or arced terminals; a "rattle test" may also indicate internal component failure in this specific current relay style.

What happens if the pick-up amperage is incorrect?
If the relay fails to pick up at 24.75A, the start capacitor may not engage, leading to a locked rotor condition and potential compressor damage.

Is this relay compatible with non-Copeland compressors?
While designed for Copeland systems, compatibility is determined by the specific amperage requirements of the motor; always verify the LRA (Locked Rotor Amps) and RLA (Rated Load Amps) before installation.
