## Long description

The Eti-Polam ETITEC SM T12 300/12,5 4+0 is a high-performance surge arrester engineered to provide comprehensive protection for electrical installations. By combining Type 1 and Type 2 protection capabilities, this device effectively manages transient overvoltages resulting from atmospheric discharges, such as lightning strikes, as well as internal switching operations within the power grid. Its robust design ensures that sensitive electronic equipment and distribution networks remain shielded from damaging voltage spikes, thereby enhancing the overall reliability and operational lifespan of your electrical infrastructure.
Advantages
This surge arrester offers a dual-functionality approach by integrating both coarse and fine protection into a single unit. The 4+0 configuration is specifically optimized for TN-S systems, providing a streamlined solution that simplifies installation while maintaining high safety standards. Its durable construction is built to withstand significant energy discharges, ensuring consistent performance even in demanding environments. By utilizing advanced varistor technology, the device reacts rapidly to voltage fluctuations, preventing potential damage to connected appliances and industrial machinery.
Suitable for
Residential electrical distribution boards
Commercial and office building power systems
Industrial automation and control panels
Protection of sensitive electronic equipment against lightning-induced surges
This device may not be suitable for systems with different earthing configurations, such as IT or TT networks, where specific protection topologies are required. It is also not intended for use in high-voltage transmission lines or circuits exceeding its rated voltage capacity, as this could lead to device failure or safety hazards.
Key specifications
Protection class: Type 1 + Type 2
Configuration: 4+0
Maximum continuous operating voltage: 300V AC
Impulse current: 12.5 kA
Application: Low-voltage distribution networks
The installation of this surge arrester should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is typically mounted on a standard DIN rail within the main distribution board. Ensure that the connection to the protective earth conductor is as short and direct as possible to minimize impedance and maximize the effectiveness of the surge protection. Regular visual inspection of the status indicator is necessary to confirm the device is operational.
What to consider before purchase
Verify the earthing system of your installation (TN-S)
Ensure the voltage rating matches your network requirements
Check available space on the DIN rail within your distribution board
Confirm that the discharge capacity meets the risk assessment of your location
For optimal performance, it is recommended to install the surge arrester as close as possible to the point of entry of the power supply into the building. Always ensure that the grounding system is properly maintained to allow the device to dissipate surge energy effectively.
