Product information
01
Legacy 108 A identity and successor boundary
A 45 A motor-duty profile with an OEM-listed successor that still requires matching.
Siemens 6SN1123-1AA00-0LA1 combines the 108 A module class, internal heat dissipation and a published 45 A motor rating for two duty descriptions.

02 · Successor-aware 108 A exchange path
A controlled route from 0LA1 identification to 0LA3 compatibility review.
The Siemens successor flag supports sourcing direction, but it does not remove the need to verify the installed hardware and commissioned data.
Route logic
Identify → Commission
01
Read
Capture the complete 0LA1 module and control-board nameplates.
02
Classify
Identify whether the machine uses 1PH or asynchronous motor duty.
03
Connect
Check the 50 mm² table entry, M6 PE point and 6–8 Nm torque.
06
Validate
Recommission the axis and verify current, direction, cooling and alarms.
05
Compare
Review 0LA3 mechanically, electrically and parametrically before substitution.
04
Archive
Save drive data and document every installed connector before removal.
Both published duty values are 45 A
The 108 A figure is the module class, not a second motor rated-current value.
0LA3 is an official successor
Successor status guides review; it does not prove an unchecked drop-in replacement.
Preserve the installed configuration
Control-board version, motor data, cooling and parameters remain part of the exchange boundary.
Installation note: For 6SN1123-1AA00-0LA1 replacement work, document the 1PH or asynchronous duty, control board, 50 mm² connection, M6 PE point, cooling and parameter set.
03 · FAQ
Buyer questions for Siemens 6SN1123-1AA00-0LA1
Six buyer answers focused on the legacy 108 A configuration, official successor, connection data and replacement evidence.
03
01
What motor-duty rating does Siemens publish for 6SN1123-1AA00-0LA1?
Siemens publishes 45 A for 1PH motor duty and 45 A for asynchronous motor duty. The separate 108 A value identifies the power-module class.
02
Which successor status does Siemens publish for 6SN1123-1AA00-0LA1?
The current Siemens SiePortal page identifies the later 0LA3 configuration as successor to 6SN1123-1AA00-0LA1.
03
Is the Siemens-listed 0LA3 successor automatically a drop-in replacement for 6SN1123-1AA00-0LA1?
No. The official successor listing still requires verification of the control board, motor type, connectors, internal-cooling arrangement and parameter set.
04
Which motor-cable and PE data apply to Siemens 6SN1123-1AA00-0LA1?
The official Siemens table gives a 50 mm² connection entry, an M6 protective-conductor point and a terminal tightening torque of 6–8 Nm.
05
Why must the 0LA1 suffix be preserved when ordering Siemens 6SN1123-1AA00-0LA1?
The suffix identifies the exact legacy configuration and separates 0LA1 from the later 0LA3 version. A quotation should be based on the complete nameplate, not the 108 A class alone.
06
What should a buyer send to obtain the correct Siemens 6SN1123-1AA00-0LA1 manual and quote?
Provide both nameplates, the motor category, connector photographs, cooling arrangement, saved parameters, quantity, destination and delivery requirement.

02 · Professional Product Judgment
We can often identify a product’s manufacturer, series, configuration, and function from its model number or nameplate photo. We also understand how revisions, firmware, and specifications affect compatibility and whether an alternative model can be used safely.
 
In practice
An Indian customer urgently needed a discontinued control module after several suppliers reported no stock. We identified its exact revision and function from the nameplate, checked compatible alternatives, and contacted factory and warehouse channels to locate matching inventory. After installation, the customer confirmed that the module operated correctly and later asked us to source additional spare parts.
03 · Sincere and Patient Service
Our team treats every inquiry sincerely and answers every question patiently. Even for complex requests, we verify and respond to each detail instead of providing a rushed or uncertain answer.
 
In practice
A German customer sent a mixed list of automation products and asked repeated questions about revisions, condition, photos, and delivery. Our team organized the requirements, checked every item, and replied point by point. The customer said our detailed communication made the purchasing decision easier and continued sending us new inquiries.
05
Transaction Cases
Sincere Cooperation, Long-Term Trust
Three cross-border sourcing casesshaped by verification, service and long-term trust.
01
Russia
A Russian customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.
02
India
An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.
03
Venezuela
A Venezuelan customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
