or extreme electrical surges typically lead to failure

Key Benefits Precise Electrical Control: Accurate voltage monitoring ensures the start capacitor is removed from the circuit at the optimal millisecond to prevent winding damage

Contractor-Friendly Maintenance: Features a manual feed button for system priming and a field-replaceable CTRD-101 cartridge kit to simplify internal valve repairs

Trane SWT1211 Switch 326010-701 Resistance testing with a multimeterThe Trane SWT1211 (also categorized under SWT01211) is an essential high pressure cutout switch designed for HVAC system protection. This SPST cutout switch features a single pole single throw configuration, calibrated with a 300 405# pressure range. In the field, this means the switch is engineered to interrupt the electrical circuit (cut out) when system pressure reaches 405 PSI and reset (cut in) at 300 PSI, effectively preventing compressor damage
