CONTROL Relays
phase control
PREVENT 3 PHASE MOTOR FAULT
& GUARANTEE TROUBLE-FREE
OPERATION OF INSTALLATIONS
The reliable and continuous monitoring
of three-phase networks (monitoring the
phase voltages, phase sequence, phase
unbalance and phase loss) guarantees
trouble-free and economic operation of
machines and installations.
phase Control Relays are
available in 3 housings:
Crouzet Phase Control Relays enable
in-time detection of 3-phase electrical
network faults: single-phase operating
mode or overheating caused by
network faults. They indicate the need
for maintenance and/or corrective
operations before additional costs are
incurred (production shutdown, motor
repair or replacement, etc.).

On 3-phase
supplies, the
control relays
check phase
sequence and
phase failure
preventing a
change in direction
of rotation, and
single-phase
operating modes.
They therefore
avoid overheating
faults linked to
phase imbalance.
