POWER TERMINAL BLOCKS - Rockwell Automation

1 UL1059 TERMINAL BLOCKCERTIFIED FOR HIGH FAULT SHORT CIRCUIT CURRENT RATINGSUL CATEGORY CODE XCFR2UL FILE NUMBER E40735 Rockwell Automation introducesupdated ratings for a number ofPower TERMINAL updated ratings include newshort circuit current withstandratings following updated guidelinesdescribed for UL1059 updated UL requirementspermit TERMINAL BLOCKS to be testedwith short circuit protectiondevices (fuses and circuit breakers).When the TERMINAL block, fuse orcircuit breaker, and wires areapplied together, the terminalblock may be rated with a shortcircuit current rating (withstand).This rating may be related to theapplication of specific fuse orcircuit breaker selected and thewire size for an CIRCUIT CURRENT RATINGS(SCCR)Per the requirements of the 2005 National Electric Code (NEC)and UL508A (effective April 25,2006), many electrical panels mustbe rated for their Short CircuitWithstand Rating.

2 Analyzing theSCCR of individual components,and the associated branch andfeeder overcurrent devices is amethod of determining the SCCRof an electrical Standard 508A permits aterminal block to have a 10,000 Awithstand capability without anyadditional PRODUCTR ockwell Automation has tested a number of the 1492-PD POWER TERMINAL BLOCKS todetermine their SCCR related to the new testing requirements. These are the standard PowerTerminal BLOCKS that have been used in Industrial Control new ratings for these BLOCKS permit their continued use in panels where the higher SCCR ratings are DATAPOWER TERMINAL BLOCKSBULLETIN 1492-PD SCCR DATA FOR USE WITHFUSES AND CIRCUIT BREAKERSHIGH FAULT SCCR RATINGS UP TO 200,000 ACERTIFIED TO UL REQUIREMENTS XCFR2 STANDARD PRODUCT For Use with FusesUL Ratings as of December 2006 TERMINAL Block DescriptionSuitable(1)SCCR (2)Cat.

10 Short-circuit current ratings may be marked on the TERMINAL block or on instructions provided with the TERMINAL block. Short-circuit current ratings have been determined based on the TERMINAL block's use within the minimum enclosure sizes as speci ed in Condition of Acceptability. (2) Short-circuit Current Rating, when noted additional conditions are provided. When larger overcurrent protection device of type or wire ofdi!erent size is used, the POWER TERMINAL block has a 10,000 amp withstand rating. Note: The rated wire range of terminals may exceedthe restrictive wire range used to provide higher SCCR.
