Single-Phase Motor Application

Overview

TeSys Giga contactors and TeSys Giga overload relays can be used to control and protect single-phase asynchronous motors.

TeSys Giga overload relay protects single-phase motor from thermal overload. Thermal overload protection must be set according to the application, see Thermal Overload Protection.

To avoid nuisance tripping, phase imbalance protection (see Phase Imbalance Protection) and ground-fault protection (see Ground Fault Protection) must be disabled.
