Replacement module for surge arrester Type1, T2 (class B, C) for PV module systems M T12 PV 550/6,25 002440520

Photovoltaic installation protection – replaceable module for surge protectors

This replaceable module is designed for type 1 and 2 surge protectors (class B, C), dedicated to photovoltaic systems. It provides effective protection against the effects of lightning strikes and surges in PV installations, minimizing the risk of damage to sensitive components. Its compact size – one module – simplifies installation and integration with existing systems.

Safety and efficiency in one

The M T12 PV 550/6.25 S module utilizes varistor technology, ensuring a fast and reliable response to sudden voltage changes. The impulse discharge current Iimp per pole is 6.25 kA, and the impulse current withstand capability Imax (8/20μs) reaches up to 40 kA. This effectively protects the circuit from overload and short circuit. The nominal discharge current In (8/20μs) is 20 kA.

• Overvoltage protection: Protects the photovoltaic installation from the effects of lightning strikes and other surges.
• Varistor technology: Fast and reliable response to voltage changes.
• Compact size: Occupies only one module, making it easy to install even in tight spaces.
• Optical indication: Optical indicator informs about the module's operation, facilitating diagnostics and maintenance.
• Versatility: Designed for DC systems, making it an ideal solution for photovoltaic installations.

Installation and specifications

The module is designed for mounting on a base (rail). The IP20 degree of protection provides adequate protection against touch and dust inside the enclosure. The weight of a single module is only 0.127 kg, which facilitates its transport and installation. The varistor technology used guarantees long-term and trouble-free operation of the device. The module has an optical indication of the operating status, which facilitates quick identification of problems in the installation.
