Schneider Electric - Zelio control

Zelio Control Monitoring and Control Relays

Zelio Control relays monitor and detect abnormal operating conditions concerning phase,current,voltage,frequency,speed,or temperature. The relays inform users of abnormal conditions, and allow them to initiate the necessary corrective actions before serious and costly breakdown can occur.

Featurres

Zelio measurement and control relays can monitor power supplies (phases, voltage, current, frequency) to protect motors and other equipment or control physical values such as level, speed and temperature.
