| Power Derating Curve | Figure 2 (Rated power is maximum continuous operating value at 70; derate power according to curve when exceeding 70) |
| Fusing Characteristic | Defined as significant increase in resistance when subjected to specified overload, causing current to drop below 1/50 of initial test current. Fusing time is the duration from applying overload to fusing. |
Fusing Time Requirements (Standard Type & High Lightning Surge Type)
| Rated Current Multiplier (x) | Fusing Time (S) | Environmental Temperature (C) |

Note: Fusing time can be customized upon user request. Refer to Table 3-2 for explosion-proof type and Table 3-3 for semi-fusing type.
Impact Resistance
When the switch K is closed and K2 is opened, repeatedly switching K1 on/off for 2 seconds each for 100 cycles, the test resistor should not become open-circuited. (See Figure 3).
Note: Capacitor C capacity based on customer requirements; default C=10uF if no special requirements. Resistor R value selected based on circuit, converted to internal resistance; resistor power rating 20W, power factor 0.8. For resistors under 10W, typically use 20W, 5.1K(5%).
