The P9625 (from the P9600 series family of IDMT/ DT relays) is a microprocessor based relay designed to monitor and detect Over currents in 3-phase applications. Typically the P9625 is wired in conjunction with external current transformers (1 per phase) of the feeder to be protected.
The adjustments and indicators are laid out such to help the user during set-up and fault finding. The adjustment for the L1 (R) for example has its corresponding red LED positioned above it so it is clear as to which phase this LED relates to. Adjustment and LED operation is explained further on the next page.
The adjustment for the Delay is a global adjustment that is connected with any one phase that exceeds the set threshold and delays the relay from energising.
A Test mode is provided (also accessible with the tamperproof transparent cover closed) to
confirm the correct operation of the internal relay. The relay will energise when the “TEST”
button is pressed and de-energise when the “RESET” button is pressed.
