ABB's S200PR current limiting miniature circuit breakers feature ring tongue lug connections
ABB's S200PR Ring Tongue family of current limiting miniature circuit breakers (MCBs) with ring tongue lug connections conforms to UL 489, CSA 22.2 No. 5 and IEC/EN 60947-2 standards. It is currently the only UL489 MCB on the market with rated current up to and including 35A for 480Y/277 VAC, and up to 63A for 240 VAC. The S200PR range Supplemental Protection conforms to UL1077, CSA 22.2 No. 235 and IEC /EN 60947-2 standards. Both ranges are available in 1-, 2-, 3- and 4-pole configurations, from 0.2A through 63A, and feature integrated captive screws that simplify the secure connection of cables, prevent installers from loosing the connection screws, provide extra protection and save time.
All markings on the Ring Tongue MCBs are permanent laser markings, clearly visible from the front even when mounted in position on the DIN rail. These miniature circuit breakers have a true Contact Position Indicator (CPI) that indicates the actual contact position, ensuring the display of fault conditions such as contacts that may be “welded” closed due to excessive fault. They also comply with the latest UL requirement for barriers of MCBs fitted with ring tongue terminals.
