ZY1 High Voltage Usage and High Breaking Capacity Thermal Cutoff Fuse Components 157C 16A Thermal Fuse

General introduction of RY series thermal fuse:

RY series thermal fuse has a certain range of temperature setting and bearing capacity to select. When the device is not working properly and will reach to the set max temperature, then the thermal fuse will cut off circuit to prevent security incidents arise. It certified products by global authoritative institutions Thermal fuse mainly used in home appliances and industrial equipment overheating protector.

Definition and model description

1 Rated Voltage(Ur):Max working voltage that the cutoff can withstand

2 Rated Current(Ir):Max working current that thermal cutoff can stand

3 Rated function Temperature(TF): The thermal-links shall be exposed in the test oven or oil bath, to Tf-12K or as declared by the manufacturer, but not higher than 2K below the lowest tolerance. Then, the ambient temperature should be stabilized for 10 minutes. After that, increasing the temperature at the speed of 0.5°C/min until the thermal-links cuts off the circuit. The test current should be ≤10mA. Then the temperature is Tf, its function temperature. According to IEC60691, thermal link has to trip off inside the tolerance of +0/-10°C.(If use PSE standard, the tolerance is +/-7°C).

4 Holding temperature(TH): When rated current flow through thermal link, it should be maintained at a temperature for 168 hours no changing the electrical conductivity. The maximum value of this temperature is called holding temperature. The normal working temperature we suggest is TF-25°C, at the same time, less than 200°C.

5 Maximum temperature(TM):The temperature that thermal link can maintain 10 minutes without re-connection of circuit. At the same time, double voltage shall be imposed. During this period, no re-functioning, flashover or breakdown shall happen.

Applications of thermal fuse:

•Home appliances

•Air conditioners, fans

•Hair dryers, hair curlers

•Laser printer

•Transformer

• Disinfecting cabinet

Production Capability, Precise Equipment

Q2:What qaulity assurance system do you use in your factory to ensure the thermal fuse quality?

A:Under IS0 9001 quality assurance system, we are producing over 200 million pcs organic type (RY type) thermal links every year. Our products got the certification of TUV, CE, PSE, KC, CB and UL. In 2013, we cooperated with UL and established a laboratory under Witness Testing Data Program. Then, we became the only one thermal fuse manufacturer in China who has a laboratory under Witness Testing Data Program (WTDP).
