Replacement module for Type 2 (class C) surge arrester for PV module systems M T2 PV 550/20 002440523

Photovoltaic installation protection – replaceable module for surge arresters&

& This replaceable module, catalog number 002440523, is a key element of the surge protection system in photovoltaic installations. Designed to work with Type T2 surge arresters, it provides effective protection of PV modules against the effects of indirect lightning strikes and switching surges. This solution is dedicated to both installers and end users who want to protect their investment in solar energy.& &

Construction and application&

& The M T2 PV 550/20 module has been specifically designed with the specific requirements of photovoltaic installations in mind. It utilizes varistor technology, which effectively suppresses surges, protecting sensitive system components. The Y-arrangement inside the module consists of three varistors, each protected by an independent thermal disconnect. This solution provides additional safety and reliability in the event of surges with high energy. This module is ideal for facilities without an external lightning protection system, where surge protection is particularly important.& &

Key features and benefits&

&

• Effective protection: Protects photovoltaic modules from damage caused by atmospheric and switching surges.
• Y-arrangement with thermal disconnects: Increases safety and reliability in extreme conditions. Each varistor has its own thermal disconnect, which will activate if the permissible parameters are exceeded.
• Varistor technology: Provides a fast and effective response to surges.
• Rated discharge current 20kA (8/20μs): Allows protection against significant voltage jumps. The maximum discharge current is as high as 40kA (8/20μs).
• Rated control voltage (Us): 500-550 V AC and 20 V DC – enables wide application in various photovoltaic installation configurations.
• Base mounting: Facilitates installation and module replacement (1 module size).
• Protection degree IP20: Provides basic protection against touch and contamination.
• Weight: Low weight (0.071 kg) facilitates transport and installation. & The rated discharge current is 20 kA (8/20 μs), and the maximum discharge current reaches as much as 40 kA (8/20 μs). The module operates at a rated control voltage Us of 500 to 550 V AC and 20 V DC, which ensures its versatility. The IP20 protection class guarantees basic protection against touch and contamination, and varistor technology provides a quick response to surges. & The M T2 PV 550/20 module is an investment in the long-term and safe operation of your photovoltaic installation. It provides peace of mind knowing that your panels are protected against potential damage caused by unforeseen electrical events.
