740001-( ) Null Plus Trailing Discharger
Part Number: 740001
The 740001-( ) series is a null plus, trailing-edge, light-weight static discharger. It consists of an aluminum shank section into which a distributed resistive element is inserted. The distributed resistive element has a composite semi-conductive carbon discharge point. The element is protected with a special thermo-fit shrink tubing to protect it against rain erosion.
Mounting: 610R Series Retainers (16700, 16820, 16760, 16900, 740015).
The set screw is supplied with a self-locking feature.
