Integrated transient voltage surge suppression (TVSS) is the number one choice for surge suppression in new construction applications. In addition to the extensive integrated SPD offering, Eaton’s surge protection product line includes a wide variety of surge current ratings, monitoring features and external enclosure options.

10 kA (IEEE Cat C3) used for the first time, however, it was used only to see if products fail safely. This safety standard covers EMI filters connected to 600 V or lower circuits. The UL 1283 is a safety standard and does include performance tests such as MIL-STD-220A Insertion Loss or Cat B3 Ringwave Let-Through Voltage tests.

TVSS (Transient Voltage Surge Suppressor) and SPD (Surge Protective Device), both refer to the device that can protect the low-voltage electrical system from damages of transients, spikes or surges (indirect lightning strike induced from power lines).

If you have a 480VAC Delta system you will need a TVSS rated for 550VAC or 660VAC (See the selection chart on the next page) 2nd - Select the TVSS kA rating. The kA rating is the amount of lightning energy the unit can handle during a lightning event. The kA rating is not a short circuit rating. The higher the kA rating the longer the

ABB TVSS (OVR range) offer the same “plus” advantages of the other System pro M compact devices, in order to get a perfect compat-ibility with all the modular range of products. All these TVSS products comply with the international standard IEC 61643-1 and the European standard EN 61643-11. They also comply with UL 1449 and CSA C22.2.

The Surgelogic® EMA Series surge protective device is a modular parallel transient voltage surge suppressor (TVSS). The EMA device has multi-stage suppression circuits consisting of field-proven, fast-acting metal oxide varistors (MOVs).

For those applications, Eaton offers the option of having their TVSS factory-installed integral to their HMTs. Mounted on the front of the trans-former enclosure to provide visual indication that the TVSS is no longer functional when the transformer is energized.

UL’s safety and performance standard for Surge Protective Devices (SPD), formerly known as Transient Voltage Surge Suppressors (TVSS), is UL 1449. This standard applies to end-users, manufacturers, and specifiers.
