Modular surge protector ETITEC CM T23 275/20 2+0 002440650

Electrical installation protection with ETITEC CM T23 275/20 2+0

This ETITEC CM T23 275/20 2+0 modular surge protector is a key element ensuring the safety and reliability of the electrical installation. Designed for mounting on a TH-35 mm DIN rail, it effectively protects against the effects of surges that can damage sensitive equipment. Its compact size – only 1 module – allows for easy integration with existing distribution boards.

This surge protector belongs to class T2, which means it is designed to protect against the indirect effects of lightning strikes and surges generated by devices inside the building. A rated discharge current of 20 kA (8/20 μs) and a maximum discharge current of 40 kA guarantee effective protection even in the event of strong disturbances. Additionally, the short-circuit strength of 25 kA ensures its stable operation in difficult conditions.

Key features and application:

• Network versatility: Designed for operation in TN-S networks, making it an ideal choice for most typical home and commercial installations. Does not work with DC, IT, TN-C or TT networks.
• Surge protection: Provides protection against surges of up to 1.5 kV, minimizing the risk of damage to connected devices.
• Optical indication: Has an optical indicator of operation, which informs about the need to replace the surge protector after a surge occurs. This facilitates diagnostics and keeps the system in full working order.
• Wires and cross-sections: Supports installations with three wires (without grounding) with a maximum cross-section of 10 mm² for solid and stranded wires and 6 mm² for flexible wires.
• Varistor technology: Uses proven varistor technology, providing a fast and effective response to surges.

Installation and safety:

Installation of the surge protector is simple and intuitive thanks to the standard mounting on a TH-35 mm DIN rail. The degree of protection IP20 provides basic protection against touching, but the device is not adapted to work in humid or dusty environments. Remember to select the correct wire cross-sections and comply with applicable standards and regulations regarding overvoltage protection. The surge protector does not have a built-in additional protection or a remote status signaling contact.
