## Long description

The Eti-Polam ETITEC C T2 275/20 4+0 RC is a high-performance Type 2 surge arrester specifically engineered for TNS electrical networks. This device acts as a critical safety component in residential and industrial power distribution systems, designed to mitigate the risks associated with transient overvoltages caused by atmospheric discharges or switching operations in the grid. By clamping voltage spikes to a safe level, it protects sensitive electronic equipment and appliances from damage, thereby extending their operational lifespan and ensuring system reliability.
Advantages
The primary advantage of this surge arrester is its robust design and high discharge capacity, which allows it to handle significant energy surges effectively. The inclusion of a remote signaling contact (RC) provides an essential monitoring feature, enabling users to receive immediate alerts if the protection module requires replacement. Its 4+0 configuration is optimized for TNS network topologies, ensuring comprehensive protection across all phases and the neutral conductor. The device is built for durability and ease of installation, making it a dependable choice for maintaining electrical safety standards in various environments.
Suitable for
Residential electrical distribution boards
Industrial automation and control panels
Protection of sensitive household electronics
Office equipment and computer networks
Commercial building power systems
This device may not be suitable for installations requiring Type 1 lightning current arresters, as it is designed specifically for secondary protection against transient overvoltages. It is also not intended for use in network configurations other than TNS, and attempting to install it in incompatible systems may result in ineffective protection or device failure.
Key specifications
Type: Type 2 surge protection device
Network compatibility: TNS
Operating voltage: 275V AC
Discharge current capacity: 20kA
Configuration: 4+0
Features: Remote signaling contact (RC)
Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within the distribution board. Ensure that the connection cables are kept as short as possible to minimize inductive voltage drops during a surge event. The remote signaling contact should be wired to a monitoring system or an indicator light to ensure that the status of the arrester can be checked periodically.
What to consider before purchase
Verify that your electrical network is a TNS system
Ensure the distribution board has sufficient space for a 4-module wide device
Check if your monitoring system is compatible with the remote signaling contact
Confirm that the voltage ratings match your local power grid requirements
For optimal performance, it is recommended to inspect the status indicator of the surge arrester regularly, especially after severe weather events. If the indicator shows that the protection module has reached its end of life, replace it immediately to maintain the safety of your electrical installation.
