Surge protection device T2 (C) ETITEC C T2 440/20 4+0 RC 002440408

Protection of electrical installations with surge limiters

The ETITEC C T2 440/20 4+0 RC surge arrester is a key element ensuring the safety and reliability of the electrical installation. This device, designed to protect against the effects of atmospheric and switching surges, finds application in residential, commercial and industrial buildings. Its construction based on varistor technology guarantees a quick and effective response to sudden voltage increases.

#### Construction and application

This arrester, mounted on a DIN TH-35 mm mounting rail, occupies 4 modules. It is designed for TN, IT and TN-S network systems. It provides protection at a level of 2 kV, and its ability to discharge discharge current reaches up to 20 kA (8/20 μs), and a maximum of 40 kA. This makes it ideal for protecting circuits powering devices sensitive to overvoltage, such as electronic equipment or control systems. Additionally, it has a contact for remote status signaling, which allows for quick identification of any damage and taking appropriate action.

#### Functionality and benefits

* **Versatility:** Compatible with various network systems (TN, IT, TN-S) – provides flexibility in application.

• High efficiency: The ability to dissipate large discharge currents (up to 40 kA) minimizes the risk of damage to connected devices.

• Status signaling: Optical indication of operation and a contact for remote signaling facilitate monitoring the device's status and quick reaction in the event of a failure.

• Safety: Protects the circuit against overload and short circuit - like most circuit breakers in this class.

• Mounting: Easy mounting on a standard DIN TH-35 mm rail – saves installers time.

• Wire cross-sections: Supports wires with a cross-section of up to 35 mm² (stranded) and 25 mm² (flexible).

• Durability: Short-circuit strength at the level of 25 kA ensures reliable operation in difficult conditions.

The ETITEC C T2 arrester is an investment in the safety and long-term protection of the electrical installation. Its solid construction and advanced functions make it a reliable solution for both professional installers and end-users who care about the safety of their equipment and installation.
