                                  What is the part code for 2.5A midrange overload for K range contactors

                                  There is none with 2.5A as midrange LR2K0308 = 1.8-2.6 LR2K0310 = 2.6-3.7

                                  LR2K0306 would not reset when in manual reset

                                   You will need to replace it as the unit is faulty

                                  What overload has a range of 1.2-1.8A that will suit a LC1K09 Contactor?

                                  LR2K0307 is the correct overload.

                                  What is the part number for the replacement overload for the LR2D1308?

                                  The part number for the replacement overload for the LR2D1308 is - LRD08

                                  LC2K0901 is that AC or DC control Contactor?

                                  AC Control
                                  LP2K0901 is the DC control 

                                  What is the replacement overload similar to LR2D1301

                                  LR2D1301 discontinued 30/11/2003. Use a LRD01.

                                  What is the replacement for LR2D1306 overload?

                                  There is no direct replacement for LR2D1306 overload, the alternative is LRD06, which will not fit existing contactor.

                                  Extra Two Stabs on the LR2K Overloads

                                  Issue:
                                  What are the extra two stabs used for on the LR2K overloads?

                                  Resolution:
                                  These stabs integrate with the coil and the NO contact on the single contactor that this unit is joined with to simplify wiring for a traditional three-wire control scheme.  Reference the attached document for further information.

                                  What is the DOL to suit the thermal overload LR2K0321?

                                  The DOL To suit the thermal overloadLR2K0321 is:
                                  LE1M35U721 for a 240V application or LE1M35N721 for a 440V application.
