Snap-on modules for K-System
By means of the overvoltage protection barrier
P-LB, the danger of subsequent coupling due to unfavourable wiring is largely averted. The device and the overvoltage protection form an electrical and mechanical unit. The spatial isolation in the switch cabinet is thus guaranteed on an unequivocal, permanent and industry-compliant basis. Only the leads of the field side and the control side must be spatially isolated from each other. This spatial isolation is already prescribed according to the intrinsically safe switch cabinet wiring. P-LB mounting in cabinets: simply plug into K-System modules.
