Copeland 998-0520-00 Motor Protector

The Copeland 998-0520-00 Motor Protector is a critical 120V electronic safety module designed to safeguard high-performance compressors from thermal overload and electrical faults. As a veteran-grade HVAC compressor protection device, this unit effectively monitors motor winding temperatures and interrupts the control circuit during excessive current or short-circuit events. This specific Copeland 120V motor protector is the designated replacement for the obsolete 071-0649-00, ensuring seamless mechanical and electrical integration into existing systems without the need for extensive field modifications.

Engineering-wise, the 998-0520-00 is an INT69 SC2 Diagnose module, featuring a robust 30-minute reset delay to allow for proper motor cooling before an automated restart. It is engineered for compatibility with a wide range of Copeland scroll compressors, including the ZR11, ZR12, ZR16, ZR19M3, ZR90K3, ZR250, and ZR300KC models. This OEM Copeland replacement part is built for demanding industrial environments, maintaining operational reliability within an ambient temperature range of -30°C to +70°C and utilizing 6.3mm flat plug connections for secure wiring in the terminal box.

• Direct Replacement Logic: Serves as the official upgrade path for 071-0649-00, 071-0615-00, and 071-0607-00 modules.
• Advanced Diagnostics: Utilizes the INT69 SC2 platform for precise detection of phase loss, short circuits, and thermal runaway.
• Broad Compatibility: Validated for use in 120V/240V control circuits across various commercial refrigeration motor protection applications.
• Industrial Endurance: Features PA glass-fiber-reinforced housing with an IP00 protection class for long-term durability in mechanical rooms.

• Is the 998-0520-00 compatible with my 24V control circuit? No, this is a 120V/240V module; a 24V circuit requires the 971-0067-00 module instead.
• What does a 30-minute reset delay signify? This delay prevents short-cycling by ensuring the motor windings have sufficiently cooled below the trip threshold before allowing a restart.
• Can I use this on a ZR300KC compressor? Yes, this module is specifically listed as a suitable protector for ZR300KC and other large scroll models.
