TeSys™ Giga Overload Relays

TeSys™ Giga electronic overload relays provide wide protection flexibility in a limited number of references that cover up to 630 amperes. Alarm and status LEDs inform users in real time. Ground fault, phase imbalance, trip class (5E, 10E, 20E, 30E), and reset type can easily be configured on the device. Units can be directly mounted to the TeSys Giga contactors or can be individually wired.
