RAG-TW.1 RAG-ST.1

Temperature monitor /

safety temperature limiter

for flue gas ducts

RAG-TW.1

RAG-ST.1

Electromechanical temperature monitor / safety temperature limiter as per

DIN EN 14597

• Safety temperature limitation, with single-pole changeover microswitch

• Switching capacity 16 (2.5) A, AC 250 V

• For installation in flue gas ducts

• Limit temperature can be checked through the viewing window in the

housing cover

• Compensation of ambient temperature at switching mechanism and

capillary tube

• Fail-safe design, rupture of the capillary tube opens the switching circuit

• Automatic (thermal) reset (RAG-TW.1)

• Internal reset facility covered by removable threaded nipple (RAG-ST1)

• Degree of protection IP43

• Push-in connection terminals

for fast installation

Notes Mounting aid Installation Instructions are enclosed in the package. Mounting location It must be ensured that there is sufficient clearance above the unit for viewing through the window, for adjusting the limit temperature and for removing and replacing the unit, if required. Mounting Fit protection pocket with flange to the flue gas duct. Insert spacer in the pocket and tighten the screw. Insert capillary tube and spacer in the protection pocket.
