UL Listed 500 Vdc Circuit Breakers
Class 500, 600
PowerPacT 500 Vdc Circuit Breakers
Designed for use on ungrounded dc systems having a maximum short-circuit
voltage of 500 Vdc or a maximum floating (unloaded) voltage of 600
Vdc. Suitable for use only with UPS (ungrounded uninterruptable power
supplies systems).
This two-level voltage
rating allows these circuit breakers to be applied to battery sources
having a short-circuit availability of 20,000 amperes or 50,000 amperes
for PowerPacT H-, J-, and L-frame DC circuit breakers at 500 Vdc.
IEC 500 Vdc rating is available on PowerPacT J-frame circuit breakers.
PowerPacT H-frame DC circuit breakers have
a fixed magnetic trip system. PowerPacT J- and L-frame DC circuit
breakers are provided with an adjustable magnetic trip that is readily
accessible by means of a single adjustment on the face of the circuit
breaker.
PowerPacT H- and J-frame circuit breakers are UL Listed for the interrupting ratings shown only if applied with three poles connected in series (series connection is external to circuit breaker). (See figure for example of diagram.)
PowerPacT L-frame circuit breakers are UL Listed for the interrupting ratings shown with two or three poles connected in series (series connection is external to circuit breaker).
note
Due to external series connection, I-Line™ circuit breakers are not available for this application.
