Capacitor bank relay module type SPCJ 4D40 1MRS 750065-MUM EN
Characteristics
One-, two- and three-phase overload stage with
definite time charcteristic
One-, two- and three-phase overload stage with
inverse (ANSI) time charcteristic
Phase unbalance protection stage with definite
time charcteristic
Phase unbalance protection stage with inverse
time charcteristic
Undercurrent protection for detection of capaci-
tor disconnection. Reconnection time with wide
setting range
Compensation for natural unbalance current
Fully selectable output relay configuration
Easy selection of appropriate operational scheme
for various applications
Numerical display of setting values, current
measured values, memorized values etc.
Continuous self-supervision of hardware and
software
Optical serial communication over the SPA bus
provides access from a higher level central unit
to all set and measured values and to memo-
rized fault values. Various events can also be se-
lected to be automatically read by a control data
communicator and printed out.
