Transient voltage surge suppressors


Solon, Ohio—ERICO now offers additional models of the TDX Series of panel protection products. The TDX200 Compact, TDX300 Modular and TDX400 Modular Series of transient voltage surge suppressors are designed for critical protection applications and exceed the IEEE C62.41.2 Scenario II single shot surge rating requirements for exposed service entrance locations—Exposure 3. They provide up to 400 kA maximum discharge current of protection.

Listed as Type 1 surge protection devices (SPDs) to UL 1449 3rd Edition, the devices can be installed within a Type 1 or 2 location in accordance with the NEC 2011. They feature a NEMA-4 weather-tight housing, which allows installation on indoor or outdoor service panels. The preconfigured connecting leads simplify installation. The unique narrow construction allows the SPD to fit between adjacent panel boards and connect via a 90-degree elbow.
