Copeland 940-0088-04 Current Relay
The Copeland 940-0088-04 Current Relay is a high-performance electromechanical component specifically engineered for HVACR compressor motor start-up sequences. This industrial-grade relay features a pick-up amperage of 33.6A and a drop-out amperage of 27.8A, ensuring precise control over the start winding during the critical initial torque phase. Built with a robust housing and high-conductivity metal contacts, this OEM replacement part provides the dependable switching required to maintain system reliability in demanding refrigeration and air conditioning applications.
For service technicians, the 940-0088-04 offers a direct-fit solution that eliminates the guesswork associated with universal components. Its compact footprint allows for seamless integration into existing control boxes, while the high current sensing accuracy protects the compressor motor from potential burnout caused by delayed winding disconnection. When high starting torque is required, this current relay delivers the consistent performance necessary to drive efficient HVAC system operations and reduce unnecessary downtime for your clients.
Key Benefits- Precise Electrical Control: Accurate 33.6A pick-up and 27.8A drop-out ratings ensure the start winding is engaged and disengaged at the optimal moment.
- OEM Compatibility: Designed specifically for Copeland compressors, ensuring a perfect electrical and physical match for professional installations.
- Enhanced Motor Protection: Prevents premature motor failure by effectively managing the high-current start-up phase.
- Durable Construction: Engineered with high-quality materials to withstand the thermal cycling and vibration typical of industrial refrigeration environments.
How do I verify if a current relay is faulty?
Technicians should check for continuity between terminals. If there is no continuity in the resting position or if the contacts are fused, the relay must be replaced. Listen for "clicking" without motor engagement as a potential sign of failure.
What happens if the drop-out amperage is incorrect?
If the relay fails to drop out at the specified 27.8A, the start winding may remain energized too long, leading to excessive heat and eventual compressor winding failure.
Is this relay compatible with universal start kits?
While universal kits exist, using the specific Copeland 940-0088-04 ensures the amperage thresholds match the compressor's original design specifications for maximum reliability.
