ABB: Heavy-duty safety switches
Designed for a wide variety of applications including food and beverage processing, material handling, and conveyors a new line of heavy-duty safety switches from the ABB Low Voltage Products division, with enclosed, maintenance-free mechanisms and touch-safe, visible blades, meet UL98, CSA, and NEMA KS-1 standards for demanding service-entrance and motor-load applications.
The 600V and 200kA rated switches use the same globally-rated bodies as the company’s rotary-style switches to provide increased performance, reliability, and safety to the heavy-duty market segment.
The switches’ touch-safe visible blades and operating mechanisms are fully enclosed and protected from dirt and debris. All enclosure types come with gaskets, are free of sharp edges, and offer a spacious interior for easier and safer wiring and installation of optional accessories.
The heavy-duty safety switches range from 30 to 1,200 Amperes, and are available as fused and non-fused, with Types 1/12/3R/4X steel or stainless steel enclosures.
The switches are maintenance-free, with the switch body, mechanism, fuse-holders, handle, and enclosure door easily and quickly replaceable.
Additional features of the new line include: dual color handles featuring highly-visible red marking clearly indicating when the switch is ON; auxiliary contacts with a mountable inside switch mechanism; optional viewing window which is factory installed in the enclosure door to safely see the status of the switch inside without opening the door; fuse adapter kits which are field adjustable to accommodate class R, L, J or T fuses.
