Double heating thermostat JUMO heatTHERM AT, model 603070/0170

• Has 2 independent fluid-filled measuring systems and is normally used as a control (TR) and monitoring device (STB or STW), predominantly in heating technology
• The safety temperature limiter (STB) must be manually unlocked after triggering, the safety temperature monitor (STW) switches back automatically
• Push-In® connection technology – installation time reduced by 50%
• Tested according to DIN 14 597 (replacing DIN 3440)
• Capillary break protection with STB and STW, if the measurement system is destroyed, the circuit opens and remains open
• Individual control range limitation
• Stable switching point position due to ambient temperature compensation
• two designs in one device: Thermostat with rigid shaft and long distance cable thermostat (FL: 2000 mm, rolled up in housing interior)

Technical data:
• Protection type: IP 54
• Switching capacity 16 A, 230 V, at least 250,000 switching cycles with TR
• Switching point deviation max. ± 5% across entire service life
