Mode Of Operation
STOP MOTOR BURNOUTS!
• Monitor voltage unbalance, high/ low voltage, phase loss, reversal,
incorrect sequencing and rapid short cycling.
• Voltage monitors are specifically
designed to protect compressor
motors and other 3-phase
loads from premature failure or
damage due to common voltage
faults. They offer complete
system protection by monitoring
both the source (front) and
load (back) side of the system
including the power, motor and
contactor lines. In addition, an
integral "delay on break timer"
guards against rapid short-
cycling at both the control circuit
and the 3-phase lines. Compact
and easy to install, the 24-
ICM400 & 24-ICM450 provide
highly reliable protection for your
valuable equipment.
