The Model 460
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. The 460’s wide operating range,
combined with UL and CE compliance, enables
quick access to domestic and global markets.
This unique microcontroller-based voltage and
phase-sensing device constantly monitors the
3-phase voltages to detect harmful power line
conditions. When a harmful condition is detected,
the MotorSaver’s output relay is deactivated after
a specified trip delay. The output relay reactivates
after power line conditions return to an acceptable
level for a specified amount of time (restart delay). The trip and restart delays prevent nuisance
tripping due to rapidly fluctuating power line conditions.
The Model 460 automatically senses whether it is connected to a 190-240V, 60Hz system, a 440-
480V, 60Hz system or a 380-416V, 50Hz system. An adjustment is provided to set the nominal line
voltage from 190-240 or 380-480VAC. Other adjustments include a 1-30 second trip delay, a 1-500
second restart delay and a 2-8% voltage unbalance trip point.
-L The 460-L is similar to a 460, but without the adjustable voltage unbalance and variable trip delay. These are fixed at 6% for unbalance and 4 seconds
for high, low and unbalanced voltage and 1 second for single phase.
-575 The 460-575 is intended for incoming power sources between 470VAC and 600VAC. Most commonly used in Eastern Canada and on generation
units that generate 600VAC power.
-MR The 460-MR is used for any application that needs to have an external manual reset button. It is equipped with a two-prong connection to hook to
a normally open pushbutton, which can be mounted outside a panel, therefore eliminating the need to open the panel to reset the unit.
-14 The 460-14 has two sets of contacts, 1 form A and 1 form B, for differing applications where two different voltages may be required, such as 5VDC for an
input to a PLC and 115VAC for an alarm.
-15 The 460-15 has two sets of contacts, 2 form A, for applications where two different units are to be controlled at once, such as a unit that has separate
contacts for a compressor and a fan.
-VBM The 460-VBM is designed so the user can set specific low and high voltage trip points. They also have a 1-30 second trip delay and 1-500 second
restart delay. The voltage unbalance is fixed at 6%.
- 400HZ The 460-400HZ is intended for applications that have a 400Hz power supply rather than 50-60Hz, such as aircraft and marine applications. It
has all the features of the regular 460, such as the variable restart delay, voltage unbalance (2-8%) and restart delay. Auto ranging from 190-480VAC.
