Description

The Trane SWT1257 Auto Limit Switch (130–160 °F) is a thermal safety device used in Trane furnaces and air handlers. Installed on the heat exchanger or flue path, it monitors internal temperature and automatically interrupts power if temperatures exceed 160 °F, resetting once it cools to 130 °F. This prevents overheating and potential equipment damage, ensuring safe furnace operation. Compatible with Trane heating systems, the SWT1257 enhances reliability, protects against thermal stress, and reduces maintenance needs. Its precise temperature control supports efficient performance and prolongs equipment life.

For an efficient and reliable HVAC system, the Trane Auto Limit Switch is a great choice for optimal system performance.
