Can the GV2 be used on single phase applications?
Tesys Contactors and Overload Relays
Yes, however you must verify that the device in question is suitable for the load to be controlled. Additionally, because these devices have single-phase sensitivity, provisions must be made to ensure nuisance tripping does not occur due to single phasing. This can be accomplished by wiring the current in series whereas all three poles of the device pass the current.
