Application 1: Inside the plug

1. Selection

• Disconnection temperature: Inside the plug, the disconnection temperature is generally selected to be 90 degrees or 100 degrees; considering that the temperature switch will have a current thermal effect when the current passes through, resulting in an early disconnection temperature, a higher disconnection temperature is selected according to different currents. For example, the ST06 model of An will trip 15 degrees in advance when a current of 10A passes through. If you want the internal temperature of the plug to trip at 90 degrees, you should actually choose a product with 90+15=105 degrees;

• Rated current: For products with a current of less than 10A, choose ST06;

• Considering that the internal space of the plug is small, it is easy to cause the problem of too small creepage distance, and the U1 package with insulating sleeve is recommended.

• The plug is generally not too large and the internal space is limited, so the long BW series is not recommended. The long product with a length of 10A reaches 20mm and cannot be installed; and the ST06 product with the same 10A is easier to install into the small space of the plug because it has a round shell with a diameter of 9mm and an insulating sleeve of 15mm.

2. Advantages

The thermal effect of current is small. Under the condition of 10A current, ST06 trips 15 degrees in advance, while long products trip about 30 degrees in advance. Therefore, the ST06 model is easier to select and has better compatibility. For example, if the long product is selected at 100 degrees, the thermal effect of current will trip 30 degrees in advance, so the actual selection of 130 degrees product is no problem for 10A products, but if it is a 5A product, the thermal effect of current is not obvious, and the early trip temperature is only about 10 degrees, which will cause the plug temperature to be too high, resulting in performance degradation, and serious fire hazards.

Application 2: Charging gun head

1. Selection

• Inside the charging gun head, the protection temperature is generally 80-100 degrees.

• Since the current passing through is very small, BW-BCP 5A and BW-ECP 2A are generally recommended.

• If the installation space is limited, choose the smaller BW-ECP.

• If there are pressure requirements for the temperature control switch, you can also choose the iron shell BW-BCM and BW-ECM.

2. Advantages

• The SAFTTY BW series has a low open circuit rate. Since the charging gun is a high-frequency electrical product, once the circuit is open, it will cause charging failure, and the cost of repair and replacement is high.

• Temperature sensitive, fast response speed

• High cost performance
