Surge protection limiter exchange module ETITEC CM T23 275/20 002440658

Electrical installation protection with ETITEC CM T23 275/20

The ETITEC CM T23 275/20 surge protector module is a key element in protecting electrical installations from the effects of overvoltages, both resulting from lightning strikes and fast transients in the network. The device is designed for mounting on a TH35 rail, taking up only one module, allowing it to be easily integrated into existing switchboards. Its task is to limit the voltage to a safe level, protecting connected devices from damage.

Construction and application

The surge protector from the CM T23 series is a Type 2 device, which means it provides indirect protection against overvoltages. It is intended for use in building installations, both residential and commercial. Thanks to its high efficiency (protection level 1.5 kV) and the ability to dissipate a peak discharge current of 20 kA (and even 40 kA), it provides comprehensive protection for sensitive electronic devices. Optical signaling of the device's status informs about its operation and the need for replacement.

Key features and benefits

• Versatility: Compatible with various network systems – TN, TN-C, TN-S, TT – making it an ideal solution for a wide range of installations.
• High efficiency: Rated voltage of 230 V AC and the highest continuous operating voltage of 275 V guarantee effective protection against overvoltages in typical operating conditions.
• Safety: Short-circuit strength at 25 kA ensures safe operation of the device in the event of a short circuit in the installation.
• Easy installation: Mounting on a base (TH35 rail) and compact size (1 module) facilitate and speed up installation.
• Transparency: Optical indication of operation allows for quick identification of the need to replace the surge protector after a voltage surge.
• High flexibility: The possibility of connecting wires with a cross-section of up to 25 mm² (single-/multi-strand) or 35 mm² (flexible) ensures compatibility with various types of cabling.

The ETITEC CM T23 275/20 surge protector is a solid and reliable solution for anyone who cares about the safety of their electrical installation and protects their devices from the effects of overvoltages.
