MODEL 263
3-Phase Monitor
Detects Phase Loss or Reversal
and Low Voltage
400Hz and Gold Contact Options
Automatic or Manual Reset
UL Recognized and CSA Certified
DESCRIPTION
The Model 263 continuously monitors 3-phase power systems
for phase loss, low voltage and phase reversal. The monitor
consists
of
a
solid-state
electromechanical relay.
Applying correct voltage and phase rotation energizes the
relay. When properly adjusted, a fault condition will cause the
relay to de-energize, even when regenerated voltage is
present.
When the fault is corrected, the Model 263 automatically
resets.
A manual reset version is also available. The SG
Model has silver with gold flash contacts for low current
applications.
The Model 263 does not require a neutral connection, and can
be used on Wye or Delta systems. Each of the five different
voltage ranges is adjustable to allow the monitor to be set for
existing conditions. NORMAL and TRIP L E D indicators are
provided to aid in adjustment and system troubleshooting.
