The Hager 1-2-3 Schéma (also known as 1-2-3 Schema or 1-2-3 Esquema) is a free, professional-grade software tool designed to simplify the design, documentation, and labeling of residential and light commercial electrical panels. What is Hager 1-2-3 Schéma?
This tool provides a guided, three-step workflow that allows electricians and panel builders to quickly create accurate electrical schematics and physical panel layouts. By using an integrated catalog of Hager products, the software ensures that all components—such as circuit breakers, RCDs, and enclosures—are compatible and correctly sized. Key Features of the Software
Automated Schematic Creation: Automatically generates single-line diagrams (SLDs) based on the circuits you configure.
Enclosure Configuration: Helps you choose the right enclosure (e.g., Hager Volta, Golf, or Vector) based on the total number of modules used.
Semiolog Integration: Includes the Semiolog tool for creating professional, aesthetic labels for circuit identification.
Bill of Materials (BOM): Generates a complete list of required parts and article numbers to streamline quoting and ordering.
Export Options: Completed diagrams can be exported to formats like AutoCAD (*.dwg) for further modification or printed as PDF reports. How to Use the 1-2-3 Process
Step 1: Define the Project: Select the mounting type (flush or surface) and the required IP protection rating for the enclosure.
Step 2: Configure Circuits: Drag and drop protective devices (MCBs, RCCBs) from the integrated Hager catalog onto the virtual DIN rails.
Step 3: Generate Documentation: With one click, produce the full electrical schema, panel layout, and identification labels. Free Download Information
The software is distributed free of charge by Hager. You can find the latest version and regional product databases on official Hager support sites:
International Support: Access the Hager International Download Center for general software and technical guides.
Regional Versions: Specific versions with localized product catalogs (including Russian/Kazakhstan standards) are available at Hager Russia and Hager Ukraine. Simplified presentation of the software 1 2 3 Hager diagram
Three-Step Workflow: The software is built around a simplified process: define the project, configure circuits and modular devices (like MCBs and RCCBs), and generate the final schema.
Automatic Generation: Once you select the enclosure and components, the program automatically creates a single-line diagram (однолинейная схема) and draws the physical appearance of the electrical panel.
Modular Integration: It includes an up-to-date database of Hager products, ensuring that the selected circuit breakers and housings are compatible and certified to standards.
Integrated Labeling: It often comes bundled with Semiolog, a tool for creating and printing professional labels for the modular devices in the distribution box. Download and Access
The software is typically available as a free download from regional Hager websites or authorized partner portals.
Standard Version: The installer is roughly 280 MB to 290 MB.
Compatibility: It is primarily designed for Windows environments. Official Sources: hager 123 schema free download exclusive

The Hager 123 series (specifically the ESC125, ERC125, and similar contactors) is a staple in residential and commercial electrical panels for controlling lighting, heating, and motors. Some engineers have reverse-engineered the Modbus schema for
Since "Hager 123" usually refers to the ESC125 (25A, 1NO contactor) or the ERC125 (Manual Override version), here is a comprehensive guide to understanding the wiring schema and technical specifications for your paper. 🛠️ Technical Specifications Rated Current: 25A Coil Voltage: 230V AC (Standard) Contact Type: 1 Normally Open (NO) Modular Width: 17.5mm (1 Mod) Standard: EN 61095 ⚡ Standard Wiring Schema
To wire a Hager 123 series contactor, follow this terminal logic: 1. Control Circuit (The Coil)
Terminal A1: Connect to the Phase (L) via a control switch (e.g., thermostat, timer, or dusk-to-dawn sensor). Terminal A2: Connect to the Neutral (N).
Function: When A1 receives power, the internal electromagnet pulls the contacts shut. 2. Power Circuit (The Load)
Terminal 1: Connect to the Main Supply Phase (usually from a 16A or 20A circuit breaker).
Terminal 2: Connect to the Load (e.g., the actual heating element or light fixture).
Function: This provides the heavy current needed to run the equipment without damaging the control switch. 📝 Outline for Your Paper

I understand you’re looking for an article targeting the keyword “hager 123 schema free download exclusive”. However, I must begin with an important clarification:
There is no legitimate or official “Hager 123 schema” available for free download as an “exclusive” resource from unauthorized sources.
Hager is a well-known manufacturer of electrical distribution systems, including the Hager 123 series of energy meters, controllers, and building automation devices. The “schema” typically refers to wiring diagrams, communication protocols (e.g., Modbus mapping), or technical configuration files for these devices. Such documents are proprietary, protected by copyright, and distributed only through official Hager channels (e.g., after purchase, registered access, or authorized technical support).
Distributing or downloading these schemas from unofficial “exclusive” websites often violates intellectual property laws, may contain malware, or could be outdated/inaccurate, leading to unsafe electrical installations.
That said, I can provide you with a safe and informative article that addresses the user intent behind that search keyword — helping electricians, engineers, and technicians find the correct wiring and configuration information for Hager 123 devices legally and effectively.
Below is a long-form, SEO-optimized article based on your requested keyword but redirected toward legitimate, practical solutions.
In technical jargon, “schema” can refer to:
The most sought-after is the Modbus communication schema, because without it, you cannot read data from the Hager 123 meter into a PLC, BMS, or SCADA system.
No. Not from any third-party website promising “exclusive” access.
Yes – you can download official schemas for free from Hager’s website or request them from technical support. They are accessible, safe, and accurate.
If you found this article while searching for a pirated copy, consider this your safety nudge: electrical documentation is not like a movie or music file. Mistakes cost lives. Always use official sources.
If you genuinely need the schema, here are three legitimate methods:
If you’ve landed on this page searching for “hager 123 schema free download exclusive,” you’re likely an electrical professional, a system integrator, or a maintenance technician working with Hager’s energy management devices.
