Surge arrester T3 (D) ETITEC D T3 275/3 1+0 RC 002440418

Protection of electrical installations with ETITEC surge limiters

The surge arrester T3 (D) ETITEC D T3 275/3 1+0 RC is a key element of the system protecting against the effects of lightning strikes and surges in electrical installations. It provides effective protection of electrical and electronic devices, minimizing the risk of damage caused by sudden voltage increases. This is particularly important in residential buildings, offices and other facilities sensitive to interference.

Construction and application

The arrester design is based on T3 technology, which means it is intended for installation at the energy distribution stage in the installation, close to the receivers. Mounting is done on a DIN TH-35 mm mounting rail, which facilitates integration with existing switchboards. This arrester has one pole and is designed to protect phase conductors. Optical signaling informs about the operation of the device, allowing for quick identification of any problems.

Key features and benefits

• High protection efficiency: Rated AC voltage of 230 V and a protection level of 1.4 kV guarantee effective protection against surges.
• High current capacity: Total discharge current (8/20) of 5 kA provides protection even with strong surge pulses.
• Universal mounting: Possibility of mounting on a standard DIN TH-35 mm rail facilitates installation in most switchboards.
• Status indication: Built-in optical indicator informs about the operation of the arrester, which facilitates diagnostics and maintenance of the installation.
• Compliance with standards: Meets the requirements of the latest standard PN-EN 61643-11, which guarantees safety and reliability of operation.
• Acceptance for different conductor cross-sections: Supports flexible conductors with a cross-section of up to 25 mm² and single- and multi-wire conductors up to 35 mm².
• Remote signaling contact: Allows connection to electrical installation monitoring systems.

The ETITEC D T3 275/3 1+0 RC arrester is a solid solution for professionals and end-users looking for reliable protection against surges in their electrical installations. Its compact size and easy installation make it an ideal choice for both new and modernized installations.
