Copeland 940-0163-16 Relay

The Copeland 940-0163-16 Relay is a specialized current relay designed for precise motor starting and electrical load management in refrigeration and air conditioning compressors. Engineered as a high-reliability HVAC compressor relay, this component monitors inrush current and ensures the start capacitor is disengaged once the motor reaches operational speed. By preventing continuous start-winding engagement, the 940-0163-16 relay protects the motor internals from thermal overload and premature winding failure. This OEM Copeland current relay is a drop-in HVAC start relay for compatible industrial and commercial power distribution systems, providing the fast response times required for cyclic heavy-load applications. Field technicians rely on this motor start relay for its tight tolerance on trip points, ensuring consistent performance across varying ambient temperatures. Whether you are performing a routine swap or diagnosing a locked rotor condition, this Copeland 940-0163-16 ensures the system maintains electrical integrity under high-torque demands.

• Ensures accurate start winding disconnection to prevent motor overheating and winding burnout.
• Built for high-torque HVAC applications, providing reliable starts in commercial refrigeration systems.
• Direct OEM replacement part ensures seamless mechanical and electrical compatibility with Copeland compressors.
• Compact industrial-grade housing facilitates easy installation within standard control boxes and tight spaces.
• Fast response circuitry protects sensitive compressor components from prolonged peak current exposure.

• How do I test a Copeland current relay for continuity? Use a multimeter to check the resistance across the coil and the normally open contacts to ensure the relay triggers correctly at the specified pick-up current.
• Can the 940-0163-16 be used as a cross-reference for other current relays? This relay is specifically calibrated for certain Copeland motor characteristics; always verify the pick-up and drop-out current values before substituting.
• What causes a current relay to fail in a refrigeration system? Frequent cycling, contact pitting from arcing, or a faulty start capacitor can lead to relay failure, often resulting in the compressor failing to start or tripping the breaker.
