Surge protection limiter exchange module ETITEC CM T23 275/20 G 002440659

Electrical installation protection with ETITEC CM T23 275/20

This ETITEC CM T23 275/20 G replaceable surge limiter module is a key element ensuring the safety and reliability of the electrical installation. Designed for rail mounting, it offers effective protection against the effects of atmospheric and switching surges. This is particularly important in residential, commercial and industrial buildings where sensitive electronic devices require solid protection.

Functionality and application

The ETITEC CM T23 275/20 G surge arrester, class T2, is designed to protect against overvoltages in TN, TN-C, TN-S and TT installations. Its task is to minimize the risk of damage to electrical and electronic devices by dissipating excess energy resulting from sudden voltage spikes. Optical indication of the device status informs about the possible operation of the arrester, which facilitates quick diagnosis and replacement if necessary. The possibility of connecting wires with a cross-section of up to 25 mm² (solid/stranded) or 35 mm² (flexible) ensures compatibility with various types of installations.

Key features and benefits

• High protection efficiency: Rated discharge current at 20 kA (8/20) and maximum discharge current of 40 kA guarantee effective protection against surges. Short-circuit strength at 50 kA provides additional safety in the event of a short circuit.
• Versatility: Compatible with various network systems (TN, TN-C, TN-S, TT), making it an ideal solution for both new installations and modernization of existing ones.
• Compact size: A 1-module wide module allows easy integration with the existing distribution board without taking up much space.
• Status indicator: Optical indication of operation facilitates quick identification of a damaged arrester and the need for its replacement.
• Safety: Protection level of 1.5 kV provides effective protection against high surges.
• Solid construction: Made of high-quality materials, which guarantees long life and reliable operation. Protection class IP20 provides basic protection against touch and ingress of solid objects.
• For professionals: Base mounting facilitates quick and safe installation in the electrical distribution board.
