Littelfuse Launches DC Disconnect Switch Product Line

November 11, 2020

Littelfuse, Inc. recently announced the introduction of its DC Disconnect Switch product line. The Littelfuse LS6 (available in 1000 and 500 V) and the LS6R (available in 1500 V) series are energy-efficient, compact disconnect switches that quickly break or resume the flow of current safely. Offered in both 250 and 400 amperage ratings, these switches prevent shock hazards when isolating circuits or repairing systems.

“The LS6 and LS6R DC disconnect switches have a streamlined design to eliminate the need for external bridging links or jumpers to lower heat dissipation,” said Craig Greeson, Littelfuse Industrial Business Unit Product Manager. “This increases energy efficiency as well as decreases installation and maintenance time for applications in photovoltaic and energy storage systems, oil and gas, railway, and uninterrupted power systems.”

The LS6R offers a patented operation system that minimizes damage caused by arcs upon disconnection to increase product reliability and longevity.

Key benefits of both the LS6 and LS6R series of DC disconnect switches include:

- a high-level disconnection insulation to provide a barrier to stop conduction when switch is in off position for added safety
- self-cleaning blade contacts that eliminate performance degradation (from increased electrical resistance over time) to ensure consistent behavior across the product’s lifespan
- an internally-located “sandwich-type” 2-contact symmetrical design to mitigate the electromagnetic force of repulsion to offer enhanced functionality in short-circuit conditions
- Meeting UL 98B, UL 94, and IEC 60947-3 standards

Put to the Ultimate Test – Part 1: Torsion Tests by HELUKABEL

DCS Put to the Ultimate Test Part 1 Torsion Tests by HELUKABEL 1 400x275

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.
