JOSEF timed overcurrent relay JL-8D/2X122A4 100-300VDC 0-9.9A board front wiring

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.

　　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.
