3TH8040-0X Siemens intermediate relay technical parameters
1: The operating voltage is not greater than 70% of the rated value.
2: The return voltage is not less than 5% of the rated value.
3: The action time is not more than 0.02S (under the rated value).
4: The return time is not more than 0.02S (under the rated value).
5: Electrical life The electrical life of the relay is not less than 10,000 times under normal load.
6: The power consumption of the DC circuit is not more than 4W, and the AC circuit is not more than 5VA.
7: The contact capacity is 50W in the DC inductive load (time constant τ=5±0.75ms) with a voltage not exceeding 250V and a current not exceeding 1A; in an AC voltage not exceeding 250V and a current not exceeding 3A The loop is 250VA (power factor CosΦ=0.4 ±0.1), allowing long-term connection of 5A current.
8: Insulation resistance
1: The insulation resistance of the following parts should be ≥300MΩ (at room temperature) when measured with an open circuit voltage 500V megohmmeter.
① Between the conductive terminal and the exposed non-live metal or shell;
②Between the moving and static contacts;
③ Between the normally open contact and the normally closed contact;
④ Between the contact and the voltage circuit.
9: medium strength
1: The lower part should be able to withstand the specified AC voltage test for 1 minute without insulation breakdown or flashover.
① 2000V/50Hz between all conductive terminals and exposed non-live metal or shell;
②1000V/50Hz between moving and static contacts;
③1000V/50Hz between the normally open contact (NO on the relay) and the normally closed contact (NC[1] on the relay);
④ 1000V/50Hz between the contact and the voltage circuit.
