The JUMO ATH-70 /N2 24-500 is a surface-mounted thermostat from the ATH series, designed for temperature monitoring and limiting in industrial heating and process applications. It operates on the fluid expansion principle, has a microswitch as the switching element, and offers a control range of 24 °C to 500 °C.

General Information

• Manufacturer: JUMO GmbH & Co. KG
• Series: ATH (Surface-mounted thermostats)
• Model: ATH-70 /N2 24-500
• Protection Class: IP54 (robust housing for industrial environments)
