Surge arrester T2 (C) ETITEC C T2 275/20 1+1 RC 002440402

Electrical installation protection with surge limiters ETITEC C

The ETITEC C T2 275/20 1+1 RC surge limiter is a key element in protecting electrical installations from the effects of surges, both caused by lightning strikes and fast transients in the network. The device is designed to work with TN-S, TT and TN systems, providing comprehensive protection in various network configurations. Its task is to limit the voltage to a safe level, protecting connected devices from damage. Installing a surge limiter is an investment in the long-term reliability and safety of the entire installation.

### Construction and application

This limiter, with a housing occupying 2 modules, is primarily used in residential installations and public buildings. Mounted on a TH-35 mm DIN rail, it provides convenient and quick installation. It has optical indication of operation, which facilitates the identification of a situation requiring intervention. Additionally, it is equipped with a contact for remote status signaling, enabling integration with monitoring and alarm systems. The rated AC voltage of 240V and the ability to dissipate a peak discharge current of 20 kA (and a maximum of 40 kA) guarantee effective protection against sudden voltage surges.

### Key features and benefits

* **Versatility:** Compatible with TN-S, TT and TN network systems – one limiter for many types of installations.

* **Effective protection:** Protection level of 1.5 kV for L-N and N-PE minimizes the risk of damage to connected devices.

* **Fast diagnostics:** Optical indication of operation facilitates problem location and quick response.

* **Remote monitoring:** Remote signaling contact allows integration with installation status monitoring systems.

* **Solid construction:** Short-circuit strength (Isccr) at 25 kA ensures resistance to overloads and short circuits.

* **Practical size:** Housing with a width of 2 modules makes it easy to install even in crowded switchboards.

* **Connection flexibility:** Support for conductors with a cross-section of up to 35 mm² (solid/stranded) and 25 mm² (flexible) ensures compatibility with various types of cabling.

* **Manufacturer credibility:** Product of the ETI Polam brand, a renowned manufacturer of electrical installation components.
