Specications
The Model 455
3-phase voltage monitor combines load and line
side monitoring to alert the user of contactor
failure or impending contactor failure. The
line side monitoring will protect the motor
from damaging line side conditions prior to the
motor starting. With other line-load side voltage
monitors, the motor must be started before a
voltage problem is detected. With the Model
455, the motor is fully protected at all times.
The motor will not start when a power problem
is present.
The Model 455 is a 3-phase, auto-ranging,
dual-range voltage monitor that protects 190-
480VAC, 50*/60Hz motors regardless of size.
The product provides a user selectable nominal
voltage setpoint and the voltage monitor automatically selects between the 200V and 400V
range. Other adjustments include a 2-30 second trip delay, a 2-300 second restart delay (and
manual restart) and a voltage unbalance trip point adjustment from 2-8%.
Four LEDs indicate the status of the Model 455: run light, undervoltage, overvoltage and
phasing fault. The Model 455 is a load and line side monitor that does not require a separate
power source for its electronics, making it much easier to install.
The Model 455 now has an infrared LED to communicate with the new Informer-MS. Just aim
the handheld diagnostic tool at the 455 to get valuable information such as real-time voltage
and voltage unbalance on both line and load sides, motor run hours, last 20 faults, last 32
motor starts, high and low voltage trip points, voltage unbalance trip point, restart and trip
delay settings, MotorSaver
