| Climatic Category | 55/155/21 |
| Low Air Pressure | 8.5kpa |
| Stability Grade | 5% |
| Limit Value of Resistance Change | Long-term test: (5%R+0.1); Short-term test: (1%R+0.05) |
| Temperature Coefficient | Standard type 350 ppm; Semi-fusing type, explosion-proof type, high lightning surge type: 35001500 ppm |
| Rated Current | I2(A)=P(W)/R() |
| Derating Curve | Rated power is the maximum value for continuous operation at 70. Power consumption is reduced according to the curve when exceeding 70. |
| Fusing Characteristic | Definition: When a specified overload is applied to the resistor, the resistance increases significantly; when the current flowing through the resistor drops to below 1/50 of the initial test current, it is called fusing. The time required from the application of the specified overload to fusing is called fusing time. This performance is called fusing characteristic. |
| Fusing Time Requirement | Under specified rated current overload conditions, fusing time should comply with the table. (See Table 3-1 for standard and high lightning surge types, Table 3-2 for explosion-proof types, Table 3-3 for semi-fusing types). Fusing time can be manufactured according to user requirements. |
| Impact Resistance | According to Figure 3, close switch K1, open switch K2. Repeatedly switch K1 on and off 100 times with the requirement of 2S on and 2S off. The test resistor should not be open-circuited. (Capacitor C capacity is selected based on customer requirements, default C=10uf. Resistor R value is selected based on the circuit, converted to internal resistance, rated power 20W, power factor 0.8, resistors below 10W generally take 20W, 5.1K(5%)). |
