Rockwell Automation released its new Allen-Bradley Bulletin 140MT motor protection circuit breakers and circuit protectors. These new motor protection products are available in sizes up to 40 amps and are designed to help industrial operators realize cost savings in their applications.
The new Bulletin 140MT products offer more enhanced Type F combination motor controller ratings when used with Bulletin 100-C and 100-E contactors, enabling assembled starters to be applied without additional branch circuit protection. Tap conductor protection ratings enable these devices to be wired with smaller conductors in group motor installations to help save costs.
These newly released products are available as motor circuit protectors for three-component starters and motor protection circuit breakers for two-component starters. Special 140MT product variants also address specific applications, such as providing protection at the output of variable frequency drives (VFD) in multi-motor applications or the protection of high-inrush, high-efficiency motors.
Part of the Allen-Bradley Modular Control System, Bulletin 140 products are available with connectors to enable direct wiring to Bulletin 100-K/C/E contactors.
Modular Control System components are tested together in various combinations to help provide users worldwide with standards compliance and certification.
