Surge protection module T3 (D) ETITEC D 255/3 MINI 002441632

Surge protection in the installation – reliability and safety

This ETITEC D 255/3 MINI surge limiter module is a key element in protecting the electrical installation, especially in places exposed to voltage surges. Designed for mounting in a socket installation box, it effectively protects sensitive devices from damage caused by overvoltages. A Class D limiter, in accordance with standards, provides protection against short-term voltage spikes up to 1.5 kV.

Functionality and design for professionals and users

The device is characterized by a compact design and easy installation in a standard recessed box. Optical signaling informs about the operation of the limiter, and an additional remote signaling contact allows integration with the installation monitoring system. The discharge current at 3 kA (L+N-PE) guarantees effective protection against most overvoltages occurring in the network. Made of high-quality materials, it ensures long-lasting and reliable operation. The maximum wire cross-section of 1.5 mm² allows connection of standard installation wires.

Key features and benefits

• Class T3 protection: Provides precise protection of devices sensitive to overvoltage with a surge voltage of up to 1.5 kV.
• Status indication: Optical indication of operation facilitates identification of the need to replace the limiter. An additional remote signaling contact allows monitoring the device's status in a smart home or building system.
• Compact dimensions: Allow easy installation in standard installation boxes without taking up much space.
• Versatility: Suitable for protecting various receivers, such as RTV equipment, computers, alarm systems or LED lighting.
• Safety: Compliance with standards ensures safe and reliable operation of the device.
• 3kA discharge current: Effectively dissipates surge energy, protecting connected devices from damage.
• Rated voltage AC 230V: Adapted to standard electrical networks in Poland and Europe.
• Protection degree IP20: Provides basic protection against accidental contact and contamination.

Application

The ETITEC D 255/3 MINI limiter is used in:

• Home installations: Protection of RTV equipment, computers, alarm systems and other sensitive devices.
• Office installations: Protection of computer equipment, servers and office equipment from overvoltages.
• Industrial installations: Protection of sensitive control and measuring electronics in industrial facilities (depending on the specifics of the installation).
• Multi-family residential buildings: Providing an additional level of protection for individual apartments and commercial premises.

Technical data (for professionals)

The L-PE/N-PE protection level is 1.7 kV, the rated AC voltage is 230 V, and the total discharge current (8/20) is 3 kA. The operation indication is optical, the protection degree (IP) is IP20, and the maximum wire cross-section is 1.5 mm². It also has a contact for remote signaling of the limiter's operation.

This limiter is an integral part of a comprehensive surge protection system, ensuring the safety and reliability of the electrical installation and protecting valuable devices from damage caused by sudden voltage spikes.
