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

                          Product Line:
                          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 overload to suit LC1D95U7 need to be 80-104A

                           Part code for the overload LRD3365

                          How to use LRD01…35 LRD33•• & LRD43•• and LRD33** as an indepentent relay?

                          The LRD relays has a solid tag to be used with LC1D** contactors. If you are not using LC1D contactors then using the following accessories you can terminate cable directly.

                          For LRD01…35 use the following part: LAD7B106
                          For LRD33•• & LRD43•• (3) use the following part: LA7D3064

                          What is the overload for the LR2D Everlink range 23-32 Amps?

                          The correct code is LRD332.

                          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.

                          Will the Compact NSX breaker be for sale in the USA or Canada?

                          Issue:
                          Where can I buy a Compact NSX breaker?

                          Product Line:
                          Circuit Breakers

                          Cause:
                          This breaker is popular overseas and there is interest in the US

                          Resolution:
                          There are no plans for a general release of the Compact NSX breaker line in North America, since the NSX is not UL Listed to UL489. (UL 489 is the standard commonly required in the US.) In the US, the Powerpact Circuit Breakers should be used (Powerpact breakers are UL, CSA and IEC-rated).

                          If an existing piece of equipment has an NSX breaker which needs replacing, we have made a few catalog numbers available for sale in the US. The list of numbers will vary based upon need. Contact your local authorized Schneider Electric distributor for assistance on your specific NSX catalog number.

                          For support on these breakers, Please see the following link to Global Operations where you can select other Countries:

                          What is difference between LC1D50U7 and LC1D50AU7?

                          Following are the differences between the LC1D50U7 and the LC1D50AU7:

                          LC1D50AU7 has everlink terminals.
                          LC1D50AU7....is slightly larger case and accommodate LRD3XX overloads
                          Whereas
                          LC1D50U7 contactors accommodate LRD33XX overloads.

                           

                          What is the part number of a 23A -32A overload to fit LC1D40U7 contactor?

                          LRD3353 is a 23A -32A overload to fit LC1D40U7 contactor.

                          What is the replacement overload similar to LR2D1301

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

                          Is the LR9D5369 overload still available

                           Yes it is

                          What is the part number for a non everlink overload with same rating as the LRD350?

                          Part number for a non everlink overload similar current rating is the LRD3357, see data sheets on both

                          What is the part number for a class 20 version of the LRD340

                           The part code LRD340L

                          What is the overload for LC1D65AU7 Contactor, when rating is 20-25A ?

                          17-25 Amps = LRD325
                          23-32 Amps =LRD332

                          What is the difference between A9D32620 and A9D33620 RCBO Acti 9 devices?

                           
                           

                          A9D33620 = SI (Super Immunised)
                          A9D32620 = Type A (AC or pulsating DC)

                          Type A RCBO = Tripping is ensured for residual sinusoidal alternating currents and residual pulsating direct currents, whether suddenly applied or slowly rising.
                          Type Si RCBO = With all the features of a Type A device, “Si” type Super Immunised earth leakage protection range has been specially developed to be used with loads or in environments causing disturbances. Examples are lightning or switching surges, harmonics generated by increasing number of loads and constant load leakage current from electronic ballasts, speed drives, computers, etc. The Si increases safety and allows improved continuity of supply.
                           

                          Can the Masterpact NT or NW type breaker be used at 400Hz or at 200Hz?

                          The Masterpact NT and NW style breakers are standard power distribution breakers and are not tested or UL listed for use at 200 Hz or 400 Hz. They are not recommended for use at any frequency except standard 50 or 60 Hzpower.
