Fenwal 01-017002-000 Thermoswitch Refrigerant Maintaining peak combustion efficiency inThe Fenwal 01 017002 000 Thermoswitch is a high precision, slow make and break thermostat designed for critical thermal control in industrial and HVACR applications. Featuring a 100F to 400F temperature range, this surface mount controller utilizes differential expansion technology where the outer stainless steel shell acts as the active sensing element, providing faster thermal response than traditional probe style units. This model serves as the
