Universal PTC overheat protection temperature sensor
SCRBH temperature-controlled PTC thermistor utilizes the characteristic that the resistance value of the PTC thermistor rises suddenly above the Curie temperature. When the ambient temperature rises abnormally, the protection circuit equipped with the PTC thermistor changes in resistance value. Connect or disconnect the circuit to protect the components.

Product Overview of PTC Thermistors for Overheating Protection
SCRBH temperature-controlled PTC thermistor utilizes the characteristic that the resistance value of the PTC thermistor rises suddenly above the Curie temperature. When the ambient temperature rises abnormally, the protection circuit equipped with the PTC thermistor changes in resistance value. Connect or disconnect the circuit to protect the components.

Application scope:
This product is widely used in situations where over-temperature protection is required. When the product is installed in equipment that requires over-temperature protection, the PTC resistance signal is transmitted to the motor protector. When the temperature approaches the insulation heat-resistant grade, the motor protector disconnects the circuit to implement protection.
Features:
Made of ultra-small PTC thermistor, it has small size, long life, good stability and high sensitivity. The technical indicators have reached the international level of similar products.
use
It can be used alone or in series to control the temperature at different points in the same circuit.
Technical data
The control temperature range is Tk60℃~Tk180℃. The control temperature Tk is set to a specification every 5°C. One to six cores can be produced according to user requirements. The SCRBHC series adopts German DIN 44080, DIN 44081, and DIN 44082 standards.

working principle
PTC thermistor has positive temperature coefficient resistance characteristics. When the temperature reaches its Curie point, the phase change of the semiconductor ceramic begins, and its resistance value increases rapidly with the increase of temperature. The change is especially obvious near the control temperature point Tk, thus serving the purpose of controlling the circuit.
It is recommended to use the thermistor sensor according to the following table (for reference only)

Fix the sensor at the location where the temperature needs to be detected (usually installed in the winding). Do not knock or squeeze the sensor chip hard during installation. Do not let the lead bear tensile force. The lead is connected to the motor junction box. It must be used in conjunction with a motor protector to control motor over-temperature.
Each chip of the three-core sensor is installed at an appropriate position in the three-phase winding, with one core installed in each phase winding.
