How to put the settings of thermal overload relay
How to put the settings of thermal overload relay
Thermal overload relays are 3 pole. The motor current flows through their bimetals (1 per phase) which are indirectly heated. Under the effect of the heating, the bimetals bend, cause the relay to trip and the position of the auxiliary contacts to change. The relay setting range is graduated in amps. In compliance with ...

CT7N Bimetallic Thermal Overload Relays for Motor Protection
Consistent and reliable protection. The consistent high quality of Sprecher. + Schuh thermal overload relays is ensured by a complex, factory current calibration procedure performed on each unit at full operating tempera- ture. Calibration is performed at the largest and smallest current the over- load can handle.

multiple of the motor current. A second overload relay may be mounted on the wye contactor if it is desired the load to be optimally protected in wye operation. The wye current is 1/3 of the rated motor current. The relay must then be set to this current. Protection Against Short-Circuit. The RW thermal overload relays must be.

bimetal thermostat
Bimetal Thermostat
Bimetal thermostat for electrical and automotive equipment overheating protection, bimetal thermostat models referred to as KSD, common such as KSD301, KSD302, KST, etc., Usually used in series with the thermal fuse. Our thermostats comply with CCC, CQC, ce, UL, ROHS, TUV, VDE, RU, pse, FCC, IEC and CB standards ... including: automatic reset, manual reset, normally open, normally closed , Adjustable type, unipolar, bipolar thermostat and etc.

Liquid Expansion Thermostat
Liquid Expansion Thermostat

When the temperature of the heating element changes, the temperature inside the temperature control part of the material (usually liquid) to produce the corresponding thermal expansion and contraction of the physical phenomenon, and the film cartridge connected to the temperature sensing portion is expanded or contracted. Use the lever principle to generate a switch on / off action. Stable and reliable, open the temperature difference is small, control the temperature control range, overload current and other performance characteristics. Liquid thermostat is mainly used for home appliances industry, electric equipment, refrigeration and other temperature control occasions.We thermostat in line with CCC, CQC, ce, UL, ROHS, TUV, IEC and CB standards ...... include: automatic reset, manual reset.
The fuse (FUSE) is overcurrent, overheat protection element, IEC127 standard it is defined as "the fuse link (fuse-link)". Its main role is to overload protection. The correct placement of the circuit fuse, the fuse will be in the current abnormally elevated to a certain height and heat of the moment, its own fuse cut off the current to protect the safe operation of the circuit. Fuses need to pass the CCC, CQC, ce, UL, ROHS, TUV, VDE, RU, pse, FCC, IEC and CB standards ...Including: current fuse, resettable fuse, Thermal fuse and car fuses ... ... and etc.

temperature sensor
Temperature Sensor

Temperature sensing is a different sensing resistor chip package inside the probe, commonly used temperature sensitive components are: thermocouple, platinum resistance, thermistor and so on. Temperature sensing customers in the design and styling, we need to select sensitive chip used, the probe dimensions and material, type and temperature of the wire. After the chip welding wire, After the probe is filled and encapsulated, a complete sensor device is formed, and the production process takes several hours. My products through: SJ 20722-1998, GJB 7396-2011, GJB 2433A-2011, ISO / TS16949: 2009 certification. ......Including: ntc temperature sensor, ptc temperature sensor, Pt100 temperature sensor, water temperature sensor, car sensor, ds18b20 sensor.

Thermistors are a class of sensitive components, divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC) according to temperature coefficient. Typical characteristics of the thermistor are temperature sensitive and exhibit different resistance values at different temperatures. Our thermistors accord: JB / T9476-1999, JB / T 9474-1999 standard ...... include: ntc, ptc, SMD thermistors, thermistor power type, resettable fuse, Motor protection thermistor, etc.
