Instantaneous trip relay

Trip relay is a type with fast activated speed, this type of relay has only 1 coil (Set Coil) so when power supply it will be close, when the power off, it will be open.

Model  RD2R RD2XR RF4R RF4XR RJ8R RJ8XR RJ4XR4*
Applications For applications where high demanding requirments in operating time (with tripping time from 8ms to 3ms) For applications where high demanding requirments in operating time (with models even tripping in less than 3 ms)
