Red Dot 71R3300 Preset Thermostatic Switch (34°F–44°F) with 25″ Capillary

The Red Dot 71R3300 preset thermostatic switch provides dependable temperature cycling without the need for manual adjustment. Because it uses a fixed (preset) setting, it’s ideal for mobile HVAC systems that require consistent and repeatable performance in heavy-duty operating conditions.

This thermostatic switch features a 25-inch capillary and operates within a 34°F–44°F temperature range, delivering stable clutch cycling with an 8°F differential. In addition, the flange base mounting design supports common installation patterns used across IHC-Navistar and other mobile HVAC applications.
