November 19, 2012 – ABB Low Voltage Products division introduced the S200PR Ring Tongue family of current limiting miniature circuit breakers (MCBs) with ring tongue lug connections. The SU200PR range conforms to UL 489, CSA 22.2 No. 5 and IEC/EN 60947-2 standards for 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, and their structural material is a more flexible, recyclable Thermoplastic.
In addition to the semiconductor and transportation industries, Ring Tongue breakers are designed for wherever secure cable connections are essential in applications where vibrations, earthquakes and shocks are common environmental challenges.
This Ring Tongue MCB family is part of the System pro M compact range of miniature circuit breakers and current devices. A full range of accessories are also available to further enhance the family compatibility.
“Our goal in developing the new Ring Tongue breakers is to address specifically our semiconductor and transportation customer requirements,” said Egon Hillermann, ABB’s local product group manager for mission critical MCBs in the US.
ABB is a leader in power and automation technologies that enable utility and industry customers to improve performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 130,000 people.
The ABB Low Voltage Products division manufactures low-voltage circuit breakers, switches, control products, wiring accessories, enclosures and cable systems to protect people, installations and electronic equipment from electrical overload.
