Copeland 998-0540-00 Limit Switch
The Copeland 998-0540-00 220F Limit Switch is a critical thermal protection component designed for commercial refrigeration and HVAC compressor safety. This discharge line thermostat monitors internal temperatures to prevent compressor overheating, effectively acting as a high-limit cutoff. Engineered with a 220°F trip point, the switch triggers when the discharge gas temperature reaches the safety threshold, interrupting the control circuit to protect the motor and internal scroll or reciprocating components from thermal breakdown. It typically features a 1/2 inch line mount and serves as a direct OEM replacement part for various Copeland ZB, ZBH, and ZBHV series models. Field-tested for durability, this switch ensures that your system operates within its designed thermal envelope, preventing costly oil carbonization and valve failure.
Key Benefits- Thermal Protection: Prevents catastrophic equipment failure by disabling the circuit at 220°F.
- Broad Compatibility: Standard 1/2" discharge line fitment for industrial and commercial units.
- Rapid Response: Precision-calibrated bimetal sensor for accurate temperature sensing.
- System Longevity: Helps maintain oil integrity by avoiding localized high-heat conditions in the compressor.
What is the reset temperature for this switch?
Most discharge line thermostats in this series are calibrated to reset once the line temperature drops approximately 40°F to 50°F below the trip point, though specific recovery times depend on ambient cooling.
Can this be used on systems other than Copeland?
While designed as a Copeland OEM part, it can technically be used in any HVACR system requiring a 220F high limit switch for a 1/2" line, provided the electrical ratings match the control circuit.
Is this switch manually or automatically reset?
The 998-0540-00 is an automatic reset switch; however, persistent tripping usually indicates a deeper system issue such as low refrigerant charge or high head pressure that must be addressed by a technician.
