Schneider TeSys Deca LRD02 0.16–0.25A Class 10A Thermal Overload Relay

Schneider TeSys Deca LRD02 0.16–0.25A Class 10A Thermal Overload Relay

Schneider Electric LRD02 is a differential thermal overload relay with an adjustable 0.16–0.25 A motor-current setting and class 10A tripping. It provides phase-loss sensitivity and one normally open plus one normally closed auxiliary contact for signalling. It mounts directly under compatible TeSys LC1D contactors; separate mounting needs the specified accessory. This relay does not replace short-circuit protection.
