TK Series Thermal Cutout Thermostats

Microtherm Sentronic TK Series Thermal Cutout Thermostats can be used as temperature monitors and controllers, current capable up to 16A. These thermostats feature an extremely robust design, universal characteristics, specifically adjustable hysteresis, and low tolerance of up to ±3%. The plastic housing, floor, and fastening are all tension-free, and the heat is applied directly to the thermo-bimetal snap-disc via the contact surface (bottom), allowing a rapid reaction. Microtherm Sentronic TK Series Thermostats vary in dimensions and mounting angles, and both the TK24 and TK24HT switches reset automatically, while the TK32 switch is manually reset.
