Surge arrester T2 (C) ETITEC C T2 440/20 3+0 RC 002440412

Surge protection for your installation

ETITEC C T2 440/20 3+0 RC surge arrester is a key element ensuring electrical safety in buildings and installations. A Class T2 device designed to protect against the effects of lightning strikes and fast voltage transients, it effectively minimizes the risk of equipment damage and ensures uninterrupted power supply. This is particularly important for sensitive electronic devices, which are becoming increasingly common in every home and business.

Construction and application

This arrester, mounted on a TH-35 mm DIN rail, occupies 3 modules and is designed to operate in TN, IT and TN-C network systems. Its construction based on varistor technology guarantees a quick response to overvoltages. Additionally, the optical indication of the device's status facilitates the identification of any failures. The rated discharge current at 20 kA (peak value) and the maximum discharge current of 40 kA provide effective protection even with strong voltage pulses. The integrated remote signaling contact allows for monitoring the device's status and a quick response in the event of its failure.

Key features and benefits

• Versatility: Compatible with various network systems (TN, IT, TN-C), making it a universal solution for many installations.
• High efficiency: Rated discharge current of 20 kA and maximum discharge current of 40 kA guarantee protection against large surges.
• Status indication: Optical indication of operation facilitates diagnostics and quick response in the event of a failure.
• Remote signaling: Remote signaling contact enables integration with monitoring and alarm systems.
• Solid construction: Made of high-quality materials, ensuring durability and reliable operation.
• Protection level: Provides a protection level of 2 kV, which is sufficient for most residential and commercial applications.
• Adapted for large diameter cables: Maximum flexible cable cross-section of 25 mm² and single/multi-wire cable of 35 mm² allows connection to cables with high load capacity.
• Short-circuit strength: It has a short-circuit strength (Isccr) of 25 kA, which increases its resistance to damage in the event of short circuits in the installation.

Thanks to these features, the ETITEC C T2 440/20 3+0 RC surge arrester is a reliable protection against overvoltages, protecting valuable electrical equipment and ensuring the safety of using the electrical installation.
