Simplifying component procurement allows OEMs and panel builders to make real economies. Rockwell Automation has extended the range of its popular 140U circuit breakers with additional IEC-types being added to the 140UE line, giving customers access to an even wider range of high quality, yet competitively priced CE-certified Moulded Case Circuit Breakers (MCCBs).
Flexible and versatile, the 140UE is suitable for switchgear applications, complementing the many other components available in the Allen-Bradley Modular Control System (MCS) Plus range. Sharing identical dimensions with the Allen-Bradley 140U range of UL498 listed MCCBs means that both ranges are fully interchangeable for machines and panels destined for European or North American markets.
Bulletin 140UE MCCBs are now available in frame sizes H, J, L, M and N, with current ratings from 16-160A, 20-250A, 200-630A, 300-800A and 600-1250A respectively. A compact, space-saving design means that Bulletin 140UE MCCBs offer a footprint up to 40% smaller than comparable current rated products from other manufacturers. Both thermal-magnetic and electronic trip types are available in both 3- and 4-pole versions, in frame sizes J, L and M. H frame sizes are available in thermal-magnetic and N frame in electronic trip versions respectively. All the devices in the Bulletin 140UE range meet IEC 60947-2, are CE Certified and are KEMA-KEUR third-party tested and certified.
A comprehensive range of internal accessories is also available for the 140UE line, including trip alarms, auxiliary contacts, under-voltage release and shunt trips. All internal accessories are easily field installable, without compromising certification or approvals. A full range of external accessories is also offered, such as plug-in adapters, terminal lugs/covers and motor operators. All Bulletin 140UE MCCBs have the option of a rotary-operating mechanism with IP66 rated interlocking door handle or flexible, cable operating mechanisms.
