but ensure the lead-wire configuration allows for continuous power when the compressor is idle to maintain the required oil temperature

It is widely used in Carrier 38-series split systems and Carlyle hermetic compressors requiring a secure three-wire interface

Durable construction prevents galvanic corrosion in commercial HVAC systems

Key Benefits Enhanced Compressor Protection: Prevents liquid slugging by separating liquid refrigerant from vapor before it reaching the compressor

or a "soft lockout" where the blower runs but the main burner never fires despite having 120v supply to the valve

Siemens Industrial Controls 3RU2136-4FB0 Relay 340155-7026 but ensure the lead-wire configurationThe Siemens 3RU2136 4FB0 is a high performance thermal overload relay engineered for heavy duty 3 phase motor protection in industrial HVACR systems. Designed as part of the SIRIUS innovation range, this Size S2 overload relay provides a reliable current setting range of 28 to 40 Amps, making it a standard choice for protecting motors against overheating due to overload or phase failure. Featuring Class 10 tripping characteristics, it ensures rapid
