Complete Protection from burning of winding
	Thermo System Thermistors are manufactured in accordance with DIN 44081 and 44082. In three phase motors, one Thermistor should be embedded in each phase. Good thermal coupling between Thermistor and winding is essential. The resistance increases sharply in the region of the nominal response temperature. Because the PTC assemblies are very small and rugged, they can be located in compact locations where protec­tion is needed, such as directly inside the motor wind­ings and can withstand standard varnish dip and bake operations and other handling. Response times ≤ 5 sec. are achieved with THERMO SYSTEM Thermistor.
	Features:
	Provides economical and reliable protection for 3-phase motors Wide range available: 60°C to 190°C switching temperature Available in compact size for easy assembly into windings Rapid response protection for electrical machines Long hysteresis free switch cycle life. Steep temperature-resistance curve characteristic allows for   simple evaluation electronics.
	Resistance-temperature diagram and main characteristics in accrodance to DIN 44081/44082
	Thermo System motor protection sensors conform to DIN 44081 or 44082 and are characterised by very high temperature sensitivity. In the range of the nominal alternating temperature the resistance increases sharply. This change can be used by a relay to disconnect the load circuit. Electronic evaluation circuits in widely varying applications are also possible. The resistance temperature diagram shows the typical characteristics of the Thermo System PTC. Load must not be applied to the thermistors as this creates a self-heating effect. At ambient temperature the resistance value of thermistors is normally between 30 and 250 Ω. At ambient temperature the resistance values have no relevance to the serviceability (functionality) at the ROT (rated operating temperature).The ROT of PTC-thermistors in the range of +60°C to +190°C progresses normally in steps of 10 K.
