> Characteristics

- DIGITAL complete operational three phase over current, ground over current,

 unbalanced load OLTC blocking, reclosing relay

- The reclosing function can be set ON/OFF and the number of times of reclosing can

 be freely designated up to three times

- Each necessary relay element can be separately enabled for selective use

- The 50B function has been built-in so that the product can be used without

 separately configuring OLTC BLOCKING.

- Output contact point maintaining time in a range of 0~200ms can be set up for each

 relay element

- Current sensing elements operate normally even under reclosing failure

- Reliability has been secured through self-diagnostic functions and permanent monitoring

 function

- RS-232C and RS-485C communication methods are supported

- An interlocking mode is provided to enable setting any of 12 output contact points as

 necessary.
