Description

TeSys K overload relays are designed to be used with TeSys K contactors to make a motor starter. These differential thermal overload relays detect over currents in the lines to the motor. 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 1.8 to 2.6 amperes. This trip current rating is calibrated per Class 10A. Mounting on DIN rail, separated from the contactor, with use of a terminal block LA7K0064 (to be ordered separately). Multi standards certified (IEC, UL, CSA, CCC, EAC).

Features

This module features a high-visibility yellow flag indicator that pops out instantly upon a fault condition. It includes a red push-button for simulation/trip testing, a blue push-button for standard stopping and manual reset, and an integrated selector dial that allows the user to switch between manual or automatic reset modes based on site requirements.
Built with a factory-integrated 1 NO + 1 NC auxiliary contact loop, this relay handles standard AC-15 pilot duties up to 690V and DC-13 signaling up to 250V. When an overload triggers a trip, the NC contact breaks the main contactor coil loop to drop the motor off the line, while the NO contact simultaneously closes to report a fault telemetry signal to a supervisory control panel or PLC.
Equipped with multi-driver screw clamp terminals (compatible with Philips No. 2, Pozidriv No. 2, and 6mm flat screwdrivers), the landing blocks accept a wire range from 0.34 mm2 up to 4 mm2 (solid or flexible). Tightening the terminal screws to the manufacturer-specified torque of 11.5 lbf-in (1.3 N-m) ensures a compression fit that accommodates cyclical thermal expansion and prevents localized resistive hot spots.
This ultra-compact module measures just 45mm wide, 58mm high, and 65mm deep, clipping directly onto the base terminals of standard TeSys K contactors (LC1K, LP1K, LC7K, and LP4K series). This plug-and-play mechanical alignment minimizes panel space requirements and eliminates the need for interconnecting jumper wires, while an independent base adapter (LA7K0064) allows for separate DIN rail or backplate mounting if required.
