Description
The Trane SWT01403 Low Pressure Control Switch 120/240 VA is used to monitor low-pressure conditions in refrigeration and cooling equipment. It work by sensing system pressure and opening the electrical circuit when pressure falls below a preset level, then closing it once normal pressure is restored to allow operation. Commonly used in air conditioners, heat pumps and refrigeration units where pressure protection is essential. The compressor protection, pressure monitoring, and improved system safety support maintain stable and efficient performance in HVAC systems.
