What Emerson says about new

Underwriters Laboratory (UL) requirements

– Liebert, Edco and PowerSure brands of surge protection devices have been tested and certified to comply with the new Underwriters Laboratory (UL) safety standards without modifications.

– Products have long met or exceeded UL 1449 Third Edition and meet 2012 requirements of UL 1283 Fifth Edition for electromagnetic interference filters;

– UL 1449 Third Edition says surge suppression products formerly identified as Transient Voltage Surge Suppressors (TVSS) will be termed Surge Protective Devices (SPDs);

– Revised standard combines all categories of SPDs into a system of categorization based, in part, on the location within a distribution system where they are to be installed; and

– UL changed clamp voltage testing from 6 kV, 500 A to 6 kV, 3,000 A: six-times more surge current.

Emerson Network Power, a business of Emerson (NYSE:EMR) and provider of enabling Business-Critical Continuity says its Liebert, Edco and PowerSure brands of surge protection devices have been tested and certified to comply with the new Underwriters Laboratory (UL) safety standards without requiring product modifications.

"Emerson typically meets or exceeds regulatory standards years in advance of their effective date of compliance," said Sarah Beadle, director of marketing, for the Surge Protection business of Emerson Network Power. Beadle says the products have long met or exceeded UL 1449 Third Edition, and are compliant with 2012 requirements of UL 1283 Fifth Edition for electromagnetic interference filters. "Few, if any other companies can make that claim," she says. UL 1449 Third Edition specifies that surge suppression products formerly identified as Transient Voltage Surge Suppressors (TVSS) universally will be termed Surge Protective Devices (SPDs).

The revised standard combines all categories of SPDs into a system of categorization based, in part, on the location within a distribution system where they are to be installed. Underwriters Laboratory has also changed clamp voltage testing from 6 kV, 500 A to 6 kV, 3,000 A – representing six-times more surge current.
