RS PRO Barrier Strip, Single Contact, 20 A, 600 V
This RS RPO barrier strip is used to seal the open side of a terminal block at the end of an assembly. This insulates the exposed metal components while also providing a secure mechanical stop on the DIN rail.
The strip's interlocking pins keep the cover firmly attached to the terminal block while allowing for easy insertion and removal. The inserts are suitable for use in demanding environments as they're made of zinc-plated passivated steel, which is corrosion and oxidation-resistant. The polyamide (PA) body material is resistant to wear and tear, giving you a product that will last a long time.
For convenient installation, the strip attaches easily to flat surfaces or small DIN rails. You can use this component for a wide range of electrical applications.
