mining type field isolators were developed for harsh site conditions where the
standard external door handles are often damaged, resulting in the compromise
of safety and operational reliability. This solution negates the need for an
external door-interlocked handle by utilizing a sliding mechanism which
operates directly on the isolator toggle, whilst retaining the door interlock
feature. The sliding mechanism also features lock-out provision and visual
ON/OFF status of the isolator.
features include emergency stop button, ammeter, isolator auxiliary contacts,
etc. The enclosures are rated for outdoor applications in various steel options
including mild steel, 3CR12 and 304 stainless steel. In addition, full size
canopies are also available, and in severe cases fitted with a pvc curtain in front
of the field isolator.
