Modular surge protector ETITEC EM T2 PV 1100/20 Y RC 002440624

Photovoltaic installation protection – surge arrester ETITEC EM T2 PV 1100/20 Y RC

This modular surge arrester from the ETITEC EM T2 PV series is a key element ensuring the safety and reliability of a photovoltaic installation. Designed for mounting on a TH-35 mm DIN rail, it effectively protects against the effects of surges that can damage sensitive components of the PV system. Its compact size – only 3 modules – makes it easy to integrate with existing infrastructure.

This arrester is particularly important in photovoltaic systems due to their exposure to atmospheric surges and disturbances in the power grid. The rated discharge current of 20 kA (8/20) guarantees effective protection against sudden voltage spikes, and the protection level of 4.2 kV provides a high degree of safety. Optical signaling informs about the operation of the device, allowing for quick identification and response in case of a problem.

Construction and mounting

Mounting is simple and intuitive thanks to the standard TH-35 mm DIN rail. The arrester has been designed for easy integration with existing switchboards, which translates into time and cost savings during installation. The maximum wire cross-section of up to 35 mm² (single-/multi-stranded) and 25 mm² (flexible) ensures compatibility with various types of cabling used in photovoltaic installations. The built-in remote signaling contact allows for monitoring the device status and integration with energy management systems.

Application and compliance

The ETITEC EM T2 PV 1100/20 Y RC arrester is intended for use in DC network circuits, making it an ideal solution for photovoltaic installations connected to the power grid. Its high DC voltage resistance (up to 1100 V) ensures safe operation even in difficult conditions. The degree of protection IP20 means that the device is protected against touching with fingers, which increases safety. The device meets the required safety standards, ensuring reliable protection of the installation and devices connected to the photovoltaic network.
