Differential Thermal Overload Relays, TeSys K
1 / 1
Manufacturer catalogue image
Product Description
Lifecycle Status:
Schneider Electric's TeSys K overload relays are designed to be used in conjunction with TeSys K contactors to create a complete motor starter. These differential thermal overload relays monitor current flow in the lines leading to the motor, and when an overcurrent is detected, they work with the contactor to disconnect power to the motor. This helps to prevent damage to the motor windings.
These overload relays feature an adjustable trip current rating of 3.7 to 5.5 amperes, calibrated per Class 10A. They are designed for mounting on DIN rail and can be separated from the contactor with the use of a terminal block LA7K0064 (sold separately).
These overload relays are multi-standard certified, meeting IEC, UL, CSA, CCC, and EAC standards, and are Green Premium compliant, adhering to RoHs/Reach regulations.
