The new Allen-Bradley E100 Electronic Motor Overload Relay can help industrial companies better protect their motors and avoid unplanned downtime. As the next generation of Allen-Bradley electronic overload relays, it more accurately measures a motor’s current load, models its temperature and shuts the motor off when it’s in danger of damage due to overheating.
Options are available to immediately detect jams and ground faults, enabling faster responses to these specific conditions. A remote reset option is also available for customers to remotely reset the overload.
The E100 overload relay comes in basic and advanced configurations. The basic model has two user-adjustable trip-class settings of 10 and 20. The advanced model has four trip class settings: 10, 15, 20 and 30. Above a sensing range of 100A, the advanced model can use external current transformer configurations to achieve a maximum rating of 800A.
The E100 overload relay is part of the Rockwell Automation integrated motor control system. It can mount directly to bulletin 500 NEMA contactors and 100-C IEC contactors up to 100A.

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.
