New from Weidmüller: the BR/SUxxxUC Series offers a complete line of UL489 CSA-C22.2 No. 5 and UL1077 CSA-C22.2 No. 235 thermal magnetic type circuit breaker products rated both AC and DC in 1, 2, and 3 pole (AC only), 1-63A (standard values) in any of B, C, or D curves for DIN rail-mounted applications. These circuit breakers are equipped with a positively trip-free snap action toggle actuation mechanism and visual status indication.
The UC Series offers rating 120/240/277/480VAC and 60 (single pole) or 125 (series double pole) VDC of high-rated interrupting capacity. This proven solution protects your wires and cables during short circuit or OL overload situations. Applications include Automotive Manufacturing, Chemical, Oil and Gas, Renewable Energy, Rail Vehicles, Automation, Pharmaceutical and Food, Steel Production, Telecom and Datacom, Lighting Equipment, and Process Control.
Weidmüller compliments this line with control and monitoring attachment modules (aux contact, bell alarm, and shunt trip) as well as a full offering of cuttable busbars and accessories in compliance with the relevant UL standards.

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.
