Used for smart home JOSEF timed overcurrent relay JL-8D/2X122A4DG 220V

Description :

　　purpose

　　Terminal block integrated circuit current relay (hereinafter referred to as current relay) is mainly used as a relay protection component in the transmission and transformation lines of generators and transformers. It serves as a starting element for AC circuit overload or short circuit in power systems, providing alarm signals or cutting off faults.

　　Technical data

　　Setting range: 0.03A~9.99A, with a step difference of 0.01A; 0.3A~99.9A, with a step difference of 0.1A

　　Action time: 1.2 times the set current, action time not exceeding 25ms;

　　Twice the set current, with an action time not exceeding 20ms

　　Return coefficient: overcurrent relay: 0.9~0.97; Undercurrent relay: 1.05~1.15.

　　Setting error: less than 2%

　　Power consumption: When the relay does not operate, the power consumption is less than 4W. When the relay operates, the power consumption is less than 5W;

　　Contact capacity: When the voltage is not greater than 250V, the continuous current of the contact is 5A; when the medium voltage is not greater than 250V, a DC circuit breaker with a time constant L/R of 5ms can disconnect 30W. In an AC circuit with a power factor COS of 04 when the voltage is not greater than 250V, it can disconnect 200VA.

　　Contact life: electrical life: 105 times, mechanical life: 106 times.

　　Insulation resistance: The live terminals of the relay are connected together, and the insulation resistance between the exposed non live terminals or the outer shell is measured with a megohmmeter with an open circuit voltage of 500V and not less than 300MQ.

　　Dielectric strength: The live terminals of the relay are connected together, and the non live terminals exposed to the outside or between the casings can withstand an effective value of 2000V, 50H AC power, which is small and lasts for 1 minute without breakdown or flashover.
