Schneider Electric LR2K0308

Schneider Electric’s LR2K0308 is a TeSys K differential thermal overload relay that provides motor-overload protection for AC circuits and TeSys K minicontactors. It is rated for a running current of 1.8–2.6 A with a class 10A trip characteristic per IEC 60947-4-1, and it includes one normally open and one normally closed auxiliary contact for signaling (1 NA + 1 NF). Designed for use with TeSys K contactors (examples include LC1K, LC7K, LP1K, LP4K), it can be mounted under the contactor or on a DIN rail with the appropriate accessories. For the protected circuit, it supports up to 690 V nominal operating voltage, while signaling circuits are rated at 690 V AC (AC-15) and 250 V DC (DC-13); the signaling path has an Ith of 6 A, and the unit specifies a 6 kV impulse withstand with about 2 W of power dissipation per pole. The LR2K0308 variant specifically targets the 1.8–2.6 A protection setting, making it suitable for compact motor-control applications in 50/60 Hz systems (≤ 400 Hz) within the TeSys LR family.
