Surge arrester T1, T2 (B, C) for PV systems ETITEC M T12 PV 1100/12,5 Y 002440511

Photovoltaic installation protection – surge arrester ETITEC M T12 PV

This three-pole ETITEC M T12 PV surge arrester is designed to protect photovoltaic installations from the effects of lightning strikes and overvoltages. Protection class Type 1+2 (B+C) provides comprehensive protection against both direct lightning strikes and overvoltages generated during PV system operation. Mounting on a TH-35 mm DIN rail simplifies integration with existing infrastructure.

Safety and efficiency in one device

This arrester is characterized by a high surge current of 12.5 kA (10/350 µs), which guarantees effective protection even in the event of strong discharges. The rated DC voltage of 1100 V is ideal for most standard photovoltaic installations. The protection level of 3.8 kV minimizes the risk of damage to system components, such as inverters or solar panels.

• Versatile application: Designed for DC (photovoltaic) systems, it offers reliable protection for installations at every stage of operation.
• Compact size: Occupies only 3 modules, allowing for easy integration with existing switchboards.
• Connection flexibility: Supports cables with a cross-section of up to 35 mm² (single-/multi-strand) and 25 mm² (flexible), ensuring compatibility with various types of cabling.
• Solid construction: Ensures long-lasting and reliable operation in demanding environmental conditions.

The ETITEC M T12 PV surge arrester is a modular device designed for mounting on a standard TH-35 mm DIN rail. Its construction provides easy access to the terminals, simplifying the installation and maintenance process. Protection class Type 1+2 (B+C) means that the device meets high standards of safety and effectiveness in protecting against overvoltages. Use in photovoltaic systems requires taking into account the specifics of DC circuits and proper selection of protection parameters to ensure optimal performance and safety of the entire installation.
