FAQ Question?What is the function of the “Class 10” rating on the LRD08 relay? Answer?The “Class 10” designation means the relay will trip within 10 seconds when the motor is subjected to an overcurrent of six times its set full-load ampere rating. This class is suitable for standard motor applications with normal starting times. Question?Can the LRD08 be mounted separately, away from a contactor? Answer?Yes, while it’s designed for direct mounting onto TeSys D contactors (like the LC1D09-D38 models), it can be mounted independently on a DIN rail using a separate terminal block adapter, such as the LAD7B106. Question?How do I switch between manual and automatic reset on this LRD08 relay? Answer?The reset mode is selected using the blue button. For manual reset, press the blue button after a trip. For automatic reset, the blue button must be in its ‘out’ or un-pressed position, and the relay will reset automatically after a cooling period. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
