Surge arrester T2 (C) - for PV systems ETITEC M T2 PV 600/20 002440620

Photovoltaic installation protection – reliability and safety

ETITEC M T2 PV 600/20 surge protector is a key element in protecting photovoltaic systems from the effects of sudden overvoltages. This device, designed for mounting on a TH-35 mm DIN rail, effectively protects against damage caused by lightning strikes or other disturbances in the grid. Its construction based on MOV (Metal Oxide Varistor) technology ensures a fast response and high efficiency in suppressing surges.

Construction and application

This surge protector, with a width of 3 modules, is designed specifically for operation in DC installations, making it an ideal solution for photovoltaic systems. Its task is to protect against overvoltages with a peak voltage of up to 1.9 kV. The optical indication of the device's status informs about its operation, which facilitates diagnostics and a quick response in the event of a failure. The maximum conductor cross-section with which the surge protector can cooperate is 35 mm² for single- and multi-wire conductors and 25 mm² for flexible conductors.

Key features and benefits

• Effective protection: Protects photovoltaic systems from damage caused by transient overvoltages, extending their lifespan and minimizing the risk of downtime.
• DC specialization: Designed specifically for operation in direct current (DC) installations, guaranteeing optimal protection of PV system components.
• Optical indication: Allows quick identification of the device's status and any failures, facilitating service and maintenance.
• DIN rail mounting: Standard mounting on a TH-35 mm DIN rail ensures easy and quick installation in electrical switchboards.
• High durability: Adapted to work with discharge currents up to 20 kA (8/20 μs), providing reliable protection even in the event of strong surges.
• Compact dimensions: Occupies only 3 modules in the switchboard, saving space.
• Compliance with standards: Meets the requirements of PL 50539-11 standard, confirming its safety and effectiveness.

The ETITEC M T2 PV 600/20 surge protector is an investment in the safety and long-term reliability of a photovoltaic system – for both the installer and the end user. It provides peace of mind resulting from the knowledge of solid protection of valuable installation components.
