Rockwell Automation Introduces Single Global Line of Circuit Breakers
- Published: Monday, 17 March 2014 15:47
Industrial automation customers worldwide can now reap the business efficiencies of standardizing on the new global line of molded-case circuit breakers, and control-circuit and load-protection devices from Rockwell Automation. The new line meets global certifications, including CE, CSA, CE and CCC. All products are RoHS compliant and feature a reduction in materials that are hazardous to the environment.
“Customers are seeking automation technology that delivers business efficiencies and improved competitiveness,” said Mike Tarnowski, business manager, Rockwell Automation. “Standardizing on our new single circuit-breaker line gives customers the performance, global standards and certifications ratings, shorter lead times, and local support needed. They now can focus less on stocking and managing multiple circuit-breaker products, and more on competing more profitably.”
The Allen-Bradley Bulletin 140G molded-case circuit breakers protect against overload, short circuit and ground-fault conditions. Eight frame sizes span a current range of 15 to 3,000 A and voltage range of 200 to 690V. All frame sizes are available in three- and four-pole versions. The line features increased short-circuit protection with coordination available for motors from 0.1 to 630 kW, fault currents up to 150 kA, and operational voltages up to 690V.
The Bulletin 140G circuit breakers enable quicker clearing of higher-level faults at higher voltage. The modular design adds installation flexibility with a full range of operators, from motor and rotary to flange operators. The interrupting capacity from 25 to 150 kA allows a single unit to address multiple applications, which helps reduce product stocking. The extended line of flexible accessories includes auxiliary and trip-unit alarm contacts, wiring terminations, and electronic trip units from 20 to 3,000 A, allowing the product to meet the requirements of applications on a global basis.
The Allen-Bradley family of miniature circuit breakers provides branch-circuit, supplemental and ground-leakage protection. This expanded portfolio for control circuit and load protection is IP20 finger safe, offers a wide array of available accessories, and features a versatile dual-cage terminal design. The Allen Bradley Bulletin 1489-M and Bulletin 1492-SPM circuit breakers are rated for 0.5 to 63 A, and available globally to machine builders.
All offer reversible line and load connections. The Bulletin 1489-M miniature circuit breaker provides branch-circuit protection with current limiting and is suitable for extreme conditions. The Bulletin 1492-SPM miniature circuit breaker protects equipment, systems and cables by quick disconnection. The Bulletin 1492-RCDA miniature circuit breaker detects and interrupts earth leakage for equipment protection.
