New abb S273-K2 3-pole miniature circuit breaker
* These breakers have the "K" time-current characteristic which considers high magnetic start-up currents from motors, transformers and other equipment. Instantaneous tripping occurs between 8 and 12 times rated current in 50/60Hz systems. The "K" characteristic is available up through 63 amperes. The "K" curve offers the best protection for the broadest range of electrical systems. The higher magnetic trip settings maximizes protection while allowing for higher in-rush currents during system startup.
* It is rated for 480Y/277 VAC, 2 Amps, Rated interrupting capacity = 6kA
These came in a lot of new spare parts out of the box so they may have a few tiny, light cosmetic marks on the body. This is an older version of the S203-K2 breaker so I do not see the IEC mark. This has the same pole spacing and trip characteristic as the S203-K2. The current version sells for $ 138.00.
