Industrial operators can realize cost savings in their applications using the new Allen-Bradley Bulletin 140MT motor protection circuit breakers and circuit protectors, which are available in sizes up to 40 amps.
The new Bulletin 140MT products offer 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 mean these devices can be wired with smaller conductors in group motor installations to save costs.
The 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, like providing protection at output of variable frequency drive (VFD) in multi-motor applications or 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 give users worldwide standards compliance and certification. The components are also backed by global sales and support.

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.
For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
