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 is the difference between the LA7D305 and LAD7305, remote control reset mechanism by flexible cable?
Issue:
Identifying differences between two similar part numbers.
Product Line:
IEC contactors and starters
Environment:
Products sold and used in the United States
Cause:
Choosing the correct part number
Resolution:
LAD7305 is for use on LRD01 to LRD35 , LR3D01 to LR3D35, and LRD313 to LRD365.
LA7D305 is for use on all other relays (except LRD01 to LRD35 and LR3D01 to LR3D35).
What is the difference between LAD703 and LA7D03
Issue:
Identifying differences between two similar part numbers
Product Line:
IEC contactors and starters
Environment:
Products sold and used in the United States
Cause:
Identifying differences between two similar part numbers
Resolution:
Both will remotely stop (trip) or electrically reset the overload, however;
LAD703 is used on Tesys overload LRD01 through LRD35 and LR3D01 to LR3D35.
LA7D03 is used on all other LR*D overload relays other than LRD01 to LRD35 and LR3D01 to LR3D35.
Do we have Type 2 Co-Ordination Chart for the LT47 overload relays?
LT47 is not an overload relay but an overcurrent relay, working on a definite time characteristic : current threshold and time based function.
We do not have Coordination type 2 tables for LT47.
However, LT47 is an overcurrent relay. It performs a motor current measurement through its internal CT. So, LT47 doesn't add impedance to the motor control circuit and the coordination only results from the characteristics of the short circuit protection (fuses or circuit-breaker) and of the contactor. So the coordination tables we publish for LTMR can be used when LT47 is used.

Can you remotely reset electronic overloads LR9D?
No. You cannot remotely reset LR9D electronic overloads.
There is no provision or attachment to wire external reset button to overload.
Is there a LE1M35N705 alternative or can coil be swapped out
The part codes you need is LE1D12N7 + LRD06
What is the alternative for the PDL Thermal Overload 56T9092 ?
The alternative is LRD05 (Note - these are not direct replacements)
What is the Din rail terminal block to suit the LRD12?
The LAD7B106 fits the LRD01 to LRD35 range.
What is the function of the LUFC00?
Issue:
What is the function of the LUFC00?
Product Line:
Digest 177 Section 18 : Conatctors and Starters IEC
Environment:
North American Products
Resolution:
The LUFC00 is a parallel wiring module that you can install in your U-line starter so that you can connect the starter to your PLC I/O modules quickly and without any need for tools. It allows for energization of the coil circuit of each power base, and an output signal from a PLC. It also provideds a `RUN` and `FAULT` status of each power base to the PLC. You can even tie each starter base to a LU9G02 spiltter box via the RJ45 connect and have the splitter feed to the PLC.
Can the LRD01 to LRD35 range be put back to manual from automatic.
This LRD range cannot be put back to Manual reset, once the overlaod has been changed from Manual (factory default) to Automatic.
Alternative Overload for the PDL56T992 (6.0-9.2A)
Either go for the LRD12 (5.0-8.0A) or the LRD14 (7.0-10.0A) depending on the size of the motor. This will not fit the old 56 Series DOL starter
