Application Range

The relay is rectifying type transient voltage relay, used as undervoltage latch-on starting element in the circuit of relay protection device, replacing DJ-100A series, DY-36C-DY-29C,DY-35 and type 36 voltage relays.

Main technical parameters

Action time: relay on the 0.5 times the measured value, the action time is not more than 0.15 s.
Contact form: 1, 1 break, 1 move in 1, 2 dynamic, 2 move off.
Contact capacity: in voltage not over 250 v, current is not more than 5 a, time constant of 5 + 0.75 ms in dc circuit, the inductive load product output contact breaking capacity of 50 w.Output contact under the above specified load, the product can reliably operate and return 5x10 times.The output contact is allowed to be switched on for a long time with 5A
