Bulletin 1489 Industrial DIN Rail Circuit Breakers
- UL489 listed for US Applications
- CSA 22.2 NO. 5.1 for Canadian Applications
- IEC 60 947-2 for IEC Applications
For today's customers building machines for use throughout the world, the new Bulletin 1489 helps with compliance for the varied circuit protection requirements. The Bulletin 1489 line is listed for branch circuit applications in the United States and Canada and approved as a miniature circuit breaker for IEC applications.
Designed to meet North American and IEC standards the 1489 product line provides a variety of configurations with current ranges of 0.5 A to 40 A and voltage ranges of 240V AC and 480Y/277V AC. The 1489 circuit breakers also have a DC rating: 1-pole 48V DC and 2-pole 96V DC series. This versatility can reduce engineering costs, save time for OEMs, panel builders and end users and can help meet safety standards.
In North America, the Bulletin 1489 meets UL 489 and CSA 22.2 No. 5.1 standards for branch circuit protection as well as IEC 60 947-2 requirements for miniature circuit breakers used in international industrial applications. To address the needs of equipment protection that are installed in electrical control panels, the new device helps with the equipment protection circuit formally only associated with UL 1077. It provides users with circuit protection from 0.5 amps to 40 amps and up to 480 volts.
For ease of installation a series of 1489 busbars (80 A) are now available, certified to UL489. These busbars are available in: single phase, two phase, and three phase versions.
As circuit protection standards evolve to meet application demands, Bulletin 1489 gives users a safer, reliable option that protects personnel, equipment and facilities from electrical hazards.
