T4PM – Three-pole TPST or four-pole FPST capillary limiting thermostat
Three-pole TPST or four-pole FPST capillary limiting thermostat with manual reset and intrinsic safety (opens the contacts in the event of breakage or loss of the capillary sensor or bulb).The thermostat automatically opens the main contacts when the sensor reaches the set temperature value, in order to avoid dangerous overheating; subsequently, once the faulty thermoregulation system has been repaired and the temperature has dropped, the thermostat can be reset manually. Possible calibration ranges: from +77°C up to +270°C Main applications Professional coffee machines, electric storage water heaters, small appliances, saunas, air heaters, centralized boilers and any other application where a maximum temperature safety thermostat with manual reset with three-pole or four-pole opening and intrinsic safety is required.
