                        Frequently Asked Questions

                        hide show

                        Is the LR9D5369 overload still available

                         Yes it is

                        What terminal protection shrouds fit the LR9F5*57 overload relays?

                        Issue:
                        What terminal protection shrouds fit the LR9F5*57 overload relays?

                        Cause:
                        Can not find it in the Digest

                        Resolution:
                        The LA9F701 protection shrouds fit the LR9F5357 and the LR9F5557 overload relays.

                        What are the wiring terminals on the IEC LRD* overload relays?

                        Tesys D line Overload Relays
                         
                        Resolution:
                        The normally closed overload contact are terminals 95 & 96; and the normally open overload contact are terminals 97 & 98.
                        T1 T2 and T3 are the load terminals. 

                        The normally closed control circuit contact will open when there is a fault, this contact is typically used in series with the control circuit. 

                        The normally open trip signal contact closes when a fault occurs which is typically used to control a pilot light, or alarm. 

                         

                        What terminal protection shrouds fit the LR9F5*63, LR9F5*67, and LR9F5*69 overload relays?

                        What is the replacement for LR2D3357?

                        What overload to suit LC1D95U7 need to be 80-104A

                         Part code for the overload LRD3365

                        What is the part number for the solid state overload relay for 185 amps for LC1F185G7?

                        The LR9F5371 has a setting range of 132-220 amps. The interconnection kit LA7F407 is required to directly mount the overload to the contactor.


                        CTA-ID : 2060527

                        How Can the LC1D50AU7 Contactor be mounted?

                        Two ways -  the LC1D50AU7 can be DIN Rail mounted and Plate mounted.

                        See the attached datasheet for further information.

                        What is the reference for the separate mounting kit for LRD4369 overload relay

                        The LRD43xx type of thermal overload relays are directly mounted to the contactors LC1D115 & LC1D150 only. There is no separate mounting kit for the LRD43xx.

                        If a separate mounting is required for the contactors LC1D115 or LC1D150 type, then LRD336xx shall be selected as these range of overload relays have indepentdent mounting and have similar setting range and are of Class 10A.
