The UL Listed thermal-magnetic molded case circuit breakers shown below are specifically 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.

The circuit breakers are suitable for use only with UPS (uninterruptable power supplies) and ungrounded systems (i.e. solar).

This two-level voltage rating allows these circuit breakers to be applied to battery sources having a short-circuit availability of 25,000 amperes for PAF circuit breakers at 500 Vdc.

PAF circuit breakers have a fixed magnetic trip range.

These 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 diagram below.

This breaker was maintained and then carefully removed by our company for an upgrade in a major company’s data center. Although this is used, this is in perfect condition, never have been tripped under fault conditions and was in service for only 6 years. This circuit breaker was protecting a 500KVA Liebert 600 series UPS.
