Surges and voltage transients are a major cause of equipment failure and system disruption. The TDS50 series surge protective devices, part of the ERITECH line of facility electrical protection products from ERICO, are designed to provide economical and reliable protection from voltage transients on solar PV systems.

They are conveniently packaged for easy installation on 35 mm DIN rail. Internal thermal disconnect devices help ensure safe behavior at end-of-life. A visual indicator flag provides user feedback in the event of such operation. As standard, the TDS50 provides a set of voltage-free contacts for remote signaling that maintenance is required. The convenient plug-in module and separate base design facilitates replacement of a failed surge module without needing to undo installation wiring.
