Abstract : 

• DC voltage operated
• Continuously adjustable
• 80 ms-300 s total range for 4 models
• High consistency In operate time
• 2 medium- (trip-) duty transfer contacts
• Maximum power consumption:

<1.2 W before operation

<2.0 W after operation

 APPLICATION : 

The RXKF 1time-delay relay is generally used in all protective relaying systems, as well as in industrial control and  process applications where low power consumption is important.

The relay is particularly suitable for definite- time overcurrent anddistance relaying.The 4 models

of RXKF 1 satisfy almost all protection and con­ trol timing requirements.

For applications involving longer pickup delay time. refer to type RXKD 2H. For use in breaker failure protection requiring shorter reset time. refer to type RXKE 1.
