Voltage Control Relays
Voltage control relays monitor input voltage level compared to a high or low
threshold preset by the user. In the “window” mode, the relays
simply check that the voltage remains within a predetermined high and low level. >Get

Phase Control Relays
Dedicated mainly to processes integrating 3-phase motors, phase control relays
enable in-time detection of 3-phase electrical network faults: single-phase
operating mode or overheating caused by network faults. > Get

Pump Control Relays
Pump control relays control pumps (single
or 3-phase) using discrete control inputs and monitor current (dry
operation and overload protection) and the state of supply phases.

Legacy Measurement Relays
These products will be obsolete as of 12/31/09 and will be replaced by the products above.
Zelio current and voltage measurement relays are designed to detect when preset
thresholds are exceeded, on AC or DC supply. >
