MOV T1+T2 module 1P N-PE for SP9x1 Iimp=12.5 kA In=12.5kA Up1.2kV SPA090N

Electrical installation protection with Hager SPA090N

This modular surge protective device (SPD) of class T1+T2, designed for mounting on a TH35 rail, is a key element ensuring the safety of the electrical installation and connected devices. It provides protection against the effects of lightning strikes and fast voltage transients, minimizing the risk of damage and downtime. It is an ideal solution for both installers and end-users looking for reliable protection.

Functionality and application

The SPA090N module is designed to work with TN-S, TT and TN-C installations. Its construction based on MOV (Metal Oxide Varistor) technology guarantees a quick and effective response to overvoltages. Optical signaling of the device status informs about its operation, facilitating diagnostics and maintenance. Application in electrical switchboards allows for central protection of multiple circuits simultaneously. Thanks to its compact size (1 module) it is easy to install even in limited space.

Key features and benefits

• Versatile protection: Class T1+T2 provides protection against both direct and indirect lightning strikes.
• High efficiency: Surge current 12.5 kA and protection level 1.7 kV guarantee effective protection against overvoltages.
• Status indication: Optical indication of operation facilitates identification of the need to replace the module after a surge.
• Compact size: Occupies only 1 module in the switchboard, making it easy to install in tight spaces.
• Universality: Compatible with different network types (TN-S, TT, TN-C), which increases its applicability.
• Safety: Compliance with IEC 61643-11 standard ensures a high level of safety.
• Durability: Made of high-quality materials guarantees long life and reliable operation.

Technical parameters in practice

Surge current 12.5 kA means the ability to safely discharge a sudden surge of current caused by a lightning strike or other voltage transient. Protection level 1.7 kV indicates the maximum voltage that can occur at the device terminals without damaging it or violating the insulation. The integrated optical signaling allows for a quick assessment of the device status – a change in color indicates the need to replace the module after the overvoltage protection has been activated. This avoids a situation where damaged protection does not perform its function during the next event.
