Hold Current：The maximum value of electric current which can be applied without resulting to trip in 25℃static-air. |
| *2 |
Maximum Rated Voltage：The maximum value of voltage that can be applied on both ends of the product at the state of trip. |
| *3 |
Maximum Rated Current：Maximum current value which can be applied to the product when the product results to trip. |
| *4 |
Trip Current：Minimum value of electric current by which the product result to trip in 25static-air. |
| *5 |
Initial Resistance：Representative value of resistance at 25. |
| *6 |
Resistance After Tripping：The maximum resistance after product has been left in the environment of 25for one hour after reactor trip has been done once. (after solder reflow) |
| *7 |
Power Dissipation：Representative value of electric power consumption at trip. (under the condition of 25℃still air inside) |
