                                                                                                                                                                                  GE CR123H317A is not a control relay. It is a thermal overload heater unit (overload relay heater element) designed for GE CR101H / CR101Y Series Manual Motor Starters. It provides motor overload protection by sensing excessive current and triggering the starter protection mechanism.

                                                                                                                                                                                  This component is installed inside a motor starter/overload relay assembly and is used to protect small motors from overheating caused by overload conditions.
