MOV T1+T2 module 1P L-N Iimp=12.5 kA In=12.5kA Imax=50kA Up1.2kV SPA090

Electrical installation protection with Hager SPA090

This modular surge protective device (SPD) type T1+T2, catalog number SPA090, is a key element ensuring the safety of the electrical installation and connected devices. Designed for mounting in distribution boards, it protects against the effects of lightning strikes and overvoltages in the network. Its compact size – only 1 module – allows for easy integration even in limited space.

Functionality and application

SPD SPA090 is a combination of type T1 and T2 surge arresters, which means it provides protection against both direct lightning strikes (T1) and overvoltages resulting from switching or disturbances in the network (T2). Designed for single-phase (L-N) installations, it effectively suppresses voltage surges, protecting sensitive electronic devices from damage. Optical signaling of the device status informs about possible operation and the need for replacement.

Parameters and characteristic features

The module is characterized by high strength parameters: surge current 12.5 kA (10/350 µs), rated current 12.5 kA and maximum discharge current 50 kA. The voltage protection level is 1.2 kV (L-N) and 1.7 kV (L-PE and N-PE), which guarantees effective protection against overvoltages. The rated AC voltage is 415 V with a maximum continuous operating voltage of 264 V. The IP20 degree of protection provides basic protection against contact.

• Versatility: Suitable for TN-C, TN-S and TT installations.
• Optical signaling: Enables quick identification of the device status and the need for replacement after operation.
• Compact dimensions: Occupies only 1 module in the distribution board, making installation easier even in tight spaces.
• High efficiency: Provides effective protection against overvoltages thanks to high strength parameters.
• Compliance with standards: The product meets the requirements of IEC 61643-11 and IEC 61643-12 standards, guaranteeing safety and reliability.
• Wide operating temperature range: From -40°C to +80°C enables operation in difficult environmental conditions.

Thanks to these features, the SPA090 module is a reliable solution for both professional installers and end-users looking for comprehensive protection of their electrical installations.
