Surge protection limiter replacement module T3 (D) MOD.ETITEC D T3 440/3 002440422

Electrical installation protection with ETITEC D T3 replaceable module

This T3 class surge limiter replaceable module is a key element in protecting the electrical installation from the effects of overvoltages, both resulting from lightning strikes and disturbances in the network. Designed for mounting on a base, it provides effective protection for devices sensitive to sudden voltage changes. Its compact dimensions and ease of replacement make it ideal for both installers and end users.

### Construction and application

The ETITEC D T3 440/3 module is designed to work with installations with a rated voltage of 400V (maximum continuous AC operating voltage is 440V). This limiter effectively protects against overvoltages with a protection level of 1.6 kV. Optical signaling informs about the device's operation, which facilitates diagnosis and quick replacement if necessary. The discharge current per pole (L+N-PE) is 5 kA, which provides high resistance to strong surge pulses.

### Key features and benefits

• Effective protection: Class T3 provides protection against residual overvoltages after the operation of a type 1 or 2 limiter.
• Easy installation and replacement: Base mounting simplifies the installation process and subsequent replacement of the damaged module.
• Optical signaling: Visual information about the device's status allows for quick identification of problems.
• Versatility: The possibility of connecting wires with a cross-section of up to 35 mm² (stranded) or 25 mm² (flexible) ensures compatibility with various types of installations.
• Compact dimensions: Dimensions of 18 x 47 x 52 mm allow for mounting in a limited space.
• Degree of protection IP20: Provides basic protection against touching solid foreign objects larger than 12.5 mm.
• No interference filter: The design without an interference filter focuses on the basic function of protecting against overvoltages, which translates into reliable operation.
