Restart Time Delay
Controllers utilize a restart timer to delay the
instantaneous re-start of
the controller. This allows
electromagnetic fields in
the motor to decay.

35% Voltage Drop
Controllers will
continue to operate if
the voltage drops by as
much as 35% of rated
voltage. This can be
critical when starting
the fire pump on
emergency power.

DC Shunt Trip
Controllers use a DC
shunt trip coil
powered from all 3
phases. The locked
rotor protector will
still operate under a
single phase
condition.

Motor Starting Types

Across-the-line
 Part-winding
 Primary reactor
 Wye-delta (open)
 Wye-delta (closed)
 Soft Start
 Autotransormer

Motor Starting Types Continued
Reactor Comparison

Reactor uses a standard electric motor
 Reduces complexity of field wiring - wired
same as across the line
 Low Power Factor makes the reactor ideal
for gen-set applications

Leading Phase Monitor™

Used on Wye-Delta (open) controllers
 Reduces open circuit transient to closed
circuit levels
 Allows you to use Wye-Delta (open) as an
option to Wye-Delta (closed)

Leading Phase Monitor™
Wye-Delta Transition Transients (typical)
Closing the Delta contactor
(run) with closing voltage
leading the Wye contactor
(start) gives you closing
currents about the same as
closed transition controllers
