Specification
Capillary non-reversible thermal fuse (further only KNTP) is a protection device with temperature sensor, which serves as a temperature limiter in appliances heated up by AC under abnormal working conditions. KNTP does not serve as a switch. KNTP is built-in single or double-pole switching capillary non-reversible fuse, that works on principle of liquid dilatation. KNTP consists of two main parts - switching mechanism and capillary temperature sensor. When the sensors environment temperature reaches the switch-off value preset by the manufacturer, electric circuit is disconnected.
Another start of the system must be done mechanically by pressing the button on the switches body, after the sensor has cooled down. It is not allowed to turn the KNTP on under el. load. Mounting of KNTP is performed by two M4 screws. There is a protection grounding pin on the cover. Only skilled personnel may recconect the system.
