2. Auxiliary power supply: This model can be connected to the auxiliary power supply.
3. Action value: The closing coil is not more than 70% of rated voltage. The trip coil is not less than 70% of rated voltage.
4. Contact capacity: 5A current can be connected for a long time. In DC circuit with voltage less than 250VDC, DC inductive load of τ=5ms 50W can be disconnected; in AC circuit with voltage less than 250VAC, COSФ=0.4 250VA can be disconnected. AC load.
5. Power consumption: no more than 5W.
6. There is an action indication.
7. Action time: Under the rated voltage, the action time is no more than 30ms.
8. Insulation resistance: Measure the insulation resistance between each exposed live terminal and the case with a megger with an open circuit voltage of 500V. The insulation resistance is not less than 300MΩ.
9. Medium strength: Each lead-out live terminal and the outer casing can withstand 2KV (effective value) 50HZ, and it will not break down for 1 minute without flashover.
Fourth, the conditions of use
1. Ambient temperature: -10 ° C ~ 50 ° C;
2, no conductive gas, no corrosive gas, no strong vibration;
