The CRITEC TDX50 SPD provides safe surge protection at affordable prices

SOLON, Ohio, March 24, 2005 — The CRITEC® TDX50 SPD provides surge ratings sufficient for even the most lightning-exposed, mission-critical sites. The TDX Series features three safety technologies to address catastrophic events, as well as TVSS failures due to normal aging; they include Transient Discriminating (TD) technology, thermal intimate MOVs and over-current fusing. The unique combination of these technologies provides longer TVSS life, which is backed by ERICO’s 10-year free replacement warranty.

The TDX50 provides unparalleled life, protection and safety with a 50kA 8/20µs surge rating, meeting the requirements of IEEE C62.41.2 Scenario II, Exposure 2 service entrance protection. The TDX unit’s 65kAIC short-circuit rating enables it to be directly connected to today’s commonly rated panels in accordance with NEC 285.6 (2002). It is NEMA LS1 specified and independently tested and verified. The TDX50 also meets the stringent safety requirements of UL 1449 Edition 2. Additionally, the product was recently approved under the new TVSS category when obtaining a UL Master Label for a building lightning protection system.

With the industry’s smallest profile, the TDX is ideal for installation between electrical panels, within stud walls or any tight location. The NEMA 4 enclosure is suitable for outdoor use and the unit requires no regular maintenance.
