Model EFZ - Earth Fault Relay
This relay is designed for protection against earth connection. Basically, when network current is in balance, resultant of currents passing through load wires is zero. For example, , all the current which reaches to consumer from phase just returns from null in a single-phase two-wire network. It is also the same in three-phase three-wire or four-wire networks. Anyhow, traveling current in wire would be fixed with symmetric or asymmetric loads. But when ...

Model UCM - Under Current Relay
When supply voltage and input sample current are connected to terminals A1, A2 and terminals K, L respectively and in addition current is in allowed range, device internal relay would be open (internal contact of terminal 15 to 18 is established), PWR and FAULT signals would be on and off ...

Borna - Model BFR - Battery Earth Fault Relay
This device is designed for protection against earth connection. When supply voltage is connected to terminals +B, -B and earth or body is connected to terminal P.E, the device internal relay is open(internal contact of terminals 15 to 18 and 25 to 28 are established) and fault signals would be off. If battery +pole is grounded, +B signal gets ON and the internal relay related to battery +pole fault closes right away (internal contact of terminal 15 to 16 ...

Model DOT - Timer Delay on Operate
Timing starts as soon as supply is connected to terminals A1 and A2. At the end of set time, OUT signal gets ON and internal relay status changes (internal contact of terminal 15 to 18 is made). As long as supply voltage is connected and has not dropped more than 40%, output remains unchanged. After de-energization, OUT signal gets OFF and internal relay reverts to its primary status and is ready for retiming (internal contact of terminal 15 to 16 is ...

Model RIT - Recycling Timer
ON timer starts timing, relay opens and ON signal gets ON as soon as supply is connected to terminals A1 and A2 (internal contact of terminal 15 to 18 is made). At the end of time adjusted by T.ON potentiometer handle, ON signal gets OFF, OFF signal gets ON and internal relay closes (internal contact of terminal 15 to 16 is made). At the end of time adjusted by T.OFF potentiometer handle, ON signal gets ON, OFF signal gets OFF and internal relay opens ...

Model ITR - Interval Timer
Timing starts, relay opens and OUT signal gets ON as soon as supply is connected to terminals A1 and A2 (internal contact of terminal 15 to 18 is made). At the end of time adjusted by DELAY potentiometer handle, OUT signal gets OFF and internal relay closes (internal contact of terminal 15 to 16 is made). Attention: In the case of de-energization during timing, internal relay also closes. After re-energization, the above steps will be ...

Model LST - Time Lag Switch (Miniature)
This device is designed for energy saving and lamps durability. It is not economical to apply simple on/off switches in many apartments and corridors in energy saving point of view because, they should be turned off again several minutes after they get ON. By use of timer type LST, one can turn on the lights by a switch press. Then at the end of adjusted time, the device turns off the lights ...
