Surge arrester T1, T2 (B, C) - for PV systems ETITEC EM T12 PV 1500/5 Y 002440582

Photovoltaic installation protection – surge arrester ETITEC EM T12 PV 1500/5 Y

This surge arrester of class T1 and T2 is a key element in protecting photovoltaic (PV) installations from the effects of lightning strikes and overvoltages. It provides protection against both direct and indirect lightning strikes, minimizing the risk of damage to sensitive PV system components such as inverters, panels and cabling. Its installation is an investment in the long-term and trouble-free operation of the entire installation.

Construction and application

The arrester is designed for mounting on a TH-35 mm DIN rail, which facilitates its integration with the existing distribution board. It is a three-pole device, designed to operate in installations with a DC voltage of up to 1500 V DC. Its construction based on MOV (Metal Oxide Varistor) technology guarantees a quick response to overvoltages and effective dissipation of impulse energy. The wire cross-section of up to 35 mm² (single-/multi-stranded) and 25 mm² (flexible) ensures compatibility with most standard cabling used in photovoltaic installations.

Key features and benefits

• Versatile protection: Protection class Type 1+2 means that the device provides protection against both large current impulses (direct hits) and smaller overvoltages (indirect hits).
• High efficiency: Impact current of 5 kA and protection level of 5 kV guarantee effective limitation of overvoltages to a safe level.
• Safety: The arrester protects the circuit against overload and short circuit – like most circuit breakers in this class.
• Easy installation: Mounting on a standard TH-35 mm DIN rail significantly simplifies installation, saving time and labor costs.
• Wide range of applications: Designed for use in photovoltaic systems with a DC voltage of up to 1500 V DC, making it a universal solution for various types of installations.
• Work optimization: Allows for safe operation of the PV system even in conditions of frequent lightning strikes.
• Durable construction: Made of high-quality materials ensuring reliable operation for a long time.
• Optical signaling: Optical indicator informs about the device status, facilitating diagnosis of any problems.

The ETITEC EM T12 PV 1500/5 Y arrester is a reliable solution for every installer and end user who cares about the safety and longevity of their photovoltaic installation.
