## Long description

The ETI ETITEC ML T123 300/12.5 3+1 is a high-performance modular surge arrester engineered to provide comprehensive protection for electrical systems against transient overvoltages. By integrating Type 1, 2, and 3 protection capabilities into a single unit, this device effectively manages energy surges caused by atmospheric discharges or switching operations, thereby safeguarding sensitive electronic equipment and electrical infrastructure.
The primary advantage of this modular surge arrester lies in its versatile multi-stage protection design, which ensures a high level of safety for both residential and industrial electrical installations. Its modular construction allows for easy maintenance and replacement of individual protection modules without the need to disconnect the entire system. The device offers reliable performance, high discharge capacity, and a compact footprint, making it an essential component for maintaining the longevity and operational stability of connected electrical devices.
Suitable for
Residential electrical distribution boards
Industrial automation and control systems
Protection of sensitive electronic appliances
Commercial building power supply networks
This device may not be suitable for high-voltage transmission lines or specialized industrial environments where surge currents significantly exceed the rated discharge capacity of 12.5 kA. It is also not intended for use in systems with operating voltages outside the specified range of the device.
Key specifications
Protection type: Type 1, 2, and 3
Configuration: 3+1 (TN-S/TT systems)
Maximum continuous operating voltage: 300 V AC
Impulse discharge current: 12.5 kA
Modular design for easy replacement
The device should be installed by a qualified electrician within the main distribution board, typically at the point of entry for the electrical supply. It must be connected in parallel with the electrical installation, ensuring that the grounding connection is as short and direct as possible to maximize surge diversion efficiency. The status indicator on the module should be checked periodically to ensure the protection elements remain functional.
What to consider before purchase
Verify the compatibility of the 3+1 configuration with your specific earthing system
Ensure the maximum operating voltage matches your local power grid requirements
Check available space in the distribution board for modular installation
Confirm that the discharge capacity meets the risk assessment of your facility
Usage recommendations
Regularly inspect the visual status indicator on the front of the modules. If the indicator changes color, the module has reached its end of life and must be replaced immediately to maintain system protection.
