Surge protection limiter replacement module T2 (C) MOD.ETITEC C T2 255/20 G 002440416

### Surge protection for your installation

The ETITEC C T2 255/20 G surge limiter exchangeable module is a key element ensuring electrical safety in residential and commercial buildings. Designed to protect against the effects of lightning strikes and voltage surges in the network, it minimizes the risk of damage to connected electrical and electronic devices. This module, mounted on a TH35 rail, is an ideal solution for both installers and end-users looking for reliable protection.

Construction and application

The surge arrester of class T2, which this module is, protects against the indirect effects of lightning strikes and against surges generated by devices inside the building. Its construction based on varistor technology ensures a quick response to sudden voltage increases, directing them to ground and preventing their spread in the installation. This module is particularly important in places exposed to frequent voltage changes or connecting sensitive electronic equipment. Optical signaling informs about the operation of the arrester, which facilitates diagnostics and replacement in case of failure.

Key features and benefits

• Versatility: Compatible with TN-S, TN-C, TT and TN network systems, allowing its use in various electrical installations.
• High efficiency: Rated discharge current of 20 kA (8/20) and maximum discharge current of 40 kA guarantee effective protection against surges with high energy. Short-circuit strength at the level of 25 kA further increases its reliability.
• Practical mounting: Compact size (1 module) facilitates mounting in electrical switchboards with limited space. Mounting is done on a standard TH35 rail.
• Universal conductors: Support for conductors with a cross-section of up to 35 mm² (stranded) and 25 mm² (flexible) ensures compatibility with most typical installations.
• Safety: Protection level of 1.5 kV effectively protects against high surges, and protection degree IP20 provides basic protection against touch and solid bodies.
• Replaceable construction: Modular design allows for quick and easy replacement of a damaged element without the need to interfere with the entire installation – saving time and costs.
• Rated AC voltage: 240 V – adapted to standard electrical networks.
• Optical signaling: Allows for quick identification of the device status – whether it has operated and needs to be replaced.

The ETITEC C T2 arrester is an investment in the safety of your electrical installation and peace of mind resulting from the protection of valuable devices. It provides reliable protection against the effects of surges, minimizing the risk of failures and costly repairs.
