Slide And Rotary Type Field Isolators For Harsh Industrial Conditions

JB Switchgear’s 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 or rotary type mechanism which operates directly on the isolator toggle or shaft, whilst retaining the door interlock feature. The sliding mechanism also features lock-out provision and visual ON/OFF status of the isolator. Optional features include an 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.

Mining type field isolators come in three standard sizes to cater for motors up to 250kW. Special requests can be accommodated where possible. A full technical data sheet with dimensions and ratings is available on request.
