Description

The Square D PowerPactL-frame circuit breaker is designed to protect electrical systems from damage caused by overloads and short circuits for distribution systems supplied by transformers and distribution systems supplied by engine generator sets. This 3 poles, 600A, 500VDC unit mount circuit breaker with breaking capacity of 50kA equipped with adjustablemagnetic trip unit specifically designed for use on ungrounded dc systems. The circuit breakers are suitable for use only with UPS (uninterruptable power supplies) and ungrounded systems. amperes at 500 Vdc This two-level voltage rating allows these circuit breakers to be applied to battery sources having a short-circuit availability of 20,000 or 50,000 This circuit breaker is UL Listed/CSA Certified for the interrupting ratings shown only if applied with three poles connected in series (series connection is xternal to circuit breaker). This modification has lugs both on line and load sides
