SURGE SUPPRESSORS PASS SWC TEST

Tempe, AZ—Circuit Components Inc. have been notified that their SAB and SPU Series of surge suppressors were recently tested and certified to IEEE C37.90 1-1989 Standard Surge Withstand Capability (SWC) and Electrical Fast Transients Tests for Protective Relays and Relay Systems.

Testing requirements were specified by Rockwell Automation Engineers. Testing was conducted through an independent testing organization under the supervision of Rockwell Automation Application Specialists. The testing set-up consisted of a complete operating SLC 500 System with Local Chassis, Power Supplies, SLC 500 Analog I/O Modules and SLC Processor. Ladder logic programs run in the SLC 500 System monitored and exercised inputs and outputs under test and logged errors or processor malfunctions.

Once CCI’s SAB and SPU Series of surge suppressors/electronic filters were incorporated into the SLC 500 System, no out-of-tolerance errors were noted. This ensured that the SCL 500 System, I/O modules and field instrumentation will continue to operate satisfactorily even when installed in the harsh environment of a substation or switchyard. The test set-up was also exposed to higher duration and peak transient values to ensure no equipment failure, even during severe lightning activity.
CCI offers a broad range of electrical suppression and filtering devices with a product line numbering over 200 models providing the most comprehensive product line for transient suppression/filtering in the in the industry.
