Rockwell Automation Introduces Allen-Bradley 1492-SP Supplementary Protectors for Supplementary Load Protection
Circuit breakers provide low-cost protection, while conserving panel space
MILWAUKEE, Dec. 5, 2001 - Responding to the manufacturing industry's need to accurately matching circuit protection levels with application requirements, complete automation leader Rockwell Automation has introduced Allen-Bradley 1492-SP Series C supplementary protectors for supplementary circuit protection.
Ideal for applications that incorporate power-limited circuits and control circuits, the new supplementary protectors are designed to protect load devices such as controllers, solenoids, power supplies and control transformers from damaging power surges. With a selectable current range from 0.5 to 40 amps, the new supplementary protectors allow users to more specifically match breakers with circuit loads.
The new Allen-Bradley 1492-SP supplementary protectors generate 10 to 20 times less "let-through" energy than a conventional breaker, resulting in less wire heating and minimizing damage to downstream components. With built-in fault detection, maintenance personnel can quickly determine and troubleshoot faults, simplifying system maintenance and reducing costly downtime.
Measuring only 80 mm in height, the compact size of the Bulletin 1492-SP supplementary protector conserves valuable panel space, allowing end-users and panel builders to incorporate more components into a single cabinet.
Designed for worldwide applications, the Allen-Bradley Bulletin 1492 supplementary protectors are UL, CSA and CE certified.
