Robertshaw 5300-088 High-Temperature Capillary Thermostat
The Robertshaw 5300-088 is a heavy-duty capillary-style temperature controller engineered for demanding HVAC, commercial, and industrial process heating applications. With a wide sensing range of 100°F to 550°F and a generous 72-inch capillary tube, this thermostat provides accurate, remote-bulb temperature sensing across extended distances — ideal for duct, oven, boiler, and process equipment installations.
Key Features
- Wide temperature sensing range: 100°F to 550°F
- 72-inch (6-foot) capillary tube for flexible remote sensing
- Open-on-rise (Open Hi) switching action — contacts open as temperature rises, providing high-limit safety control
- Integrated auxiliary switch for secondary circuit control or alarm functions
- Robust construction designed for high-temperature commercial and industrial environments
- Robertshaw quality engineering for long-term reliability
Application
The 5300-088 is well suited for use as a high-limit safety control or operating thermostat in commercial ovens, furnaces, boilers, duct systems, and process heating equipment. The open-on-rise contact configuration ensures the controlled circuit is interrupted when the sensed temperature reaches the set point, providing critical over-temperature protection. The built-in auxiliary switch adds versatility for alarm, fan, or secondary load control without requiring additional components.
