Description
Schneider LR2K0312 Thermal Overload Relay, TeSys K, 3.7 to 5.5 Amp
LR2K0312 is a TeSys LRK thermal overload relay from Schneider Electric designed to be used with TeSys K contactors to make a motor starter. When an overcurrent is detected the overload relay working with the contactor will disconnect the power to the motor. This will minimize the damage to the motor windings. This overload relay has an adjustable trip current rating of 3.7 to 5.5 amperes. This trip current rating is calibrated per Class 10A. It provides manual test & reset buttons, automatic reset, trip auxiliary contact and flag indicator. Mounting on DIN rail, separated from the contactor, with use of a terminal block LA7K0064 (to be ordered separately). Available worldwide, it is multi-standards certified (IEC, UL, CSA, CCC, EAC).
