Application Manual
The RER620 relay provides cold load timers in minutes or seconds resolution for various
application needs. In total, six Cold load timers are available to provide utmost flexibility
in cold-load inrush detection. The timer function blocks can be used for single phase or
three phase blocking. Any functions can be selected to be blocked during the cold load
timers pickup duration using the ACT/SMT.
The directional phase or ground over current protection provides a high level of selective
fault detection. The directional over current function can be used in closed ring networks
or in radial networks with generation connected remote in the system, thus giving fault
current infeed in "reverse" direction.
