Surge arrester T1, T2 (B, C) - for PV systems ETITEC EM T12 PV 1500/5 Y RC 002440583

Photovoltaic installation protection – reliability and safety

The ETITEC EM T12 PV 1500/5 Y RC surge protector is a key element in protecting photovoltaic installations from the effects of lightning strikes and surges. Designed to work with DC systems, it effectively protects sensitive components such as inverters and solar panels, minimizing the risk of failure and downtime. Mounting on a TH-35 mm DIN rail ensures convenient and quick installation.

Design and operation

This three-pole surge protector, class 1+2 (Type 1+2), offers comprehensive protection, combining the features of a first and second level surge protector. An impact current of 5 kA guarantees effective dissipation of surge energy, and a protection level of 5 kV provides a high level of safety. A built-in signaling contact informs about the need to replace the surge protector after a surge event – this is important for maintaining continuous protection.

Application and compatibility

The ETITEC EM T12 PV 1500/5 Y RC surge protector is dedicated to protecting photovoltaic installations with a DC voltage of up to 1500 V DC. It accepts wires with a cross-section of up to 35 mm² (solid or stranded) and 25 mm² (flexible), ensuring compatibility with most cabling used in PV systems. Its design makes it ideal for both new installations and upgrades to existing photovoltaic systems.
