1100A1 Standoff Insulator, Single

Part # 1100-A1

This Mar-Bal brand standoff is used to create an insulating air gap between a busbar and surrounding material, for example an enclosure gear tray. Manufactured from high grade, glass reinforced polyester which has very high mechanical strength and resistance to shattering, these insulators are especially good at preventing ‘tracking’ of current even in high temperatures and humidities. They are fitted with aluminum thread inserts, making installation quick and easy and hold UL certification, number E84767.

Installation Tips

If mounting the standoff on a gear tray, use a shakeproof washer in-between the fixing screw or bolt and the underside of the panel. This will ensure that if the standoff ever works loose you will be able to tighten it up without having to first remove the gear tray.

Caution! Do not install the washer between the insulator and the gear tray. Doing so will reduce the mechanical strength of the assembly.
