The RS PRO earth metal clamp protects electrical equipment and people working on electrical applications from shocks or power surges by diverting or grounding excess current.It has a diameter of 12 mm to 32 mm and is made from zinc-plated phosphor bronze. This plating gives it good resistance to corrosion, so the clamp is useful for damp or chemical-laden conditions. It has a stainless steel strap and is supplied with an aluminium label embossed with a safety warning that is bolted onto the clamp. The earth clamp has a maximum wire cross-section area of 10 mm² and meets electrostatic control standards for reduction of electrostatic shock.The earthing strap and clamp encircle the component you are working on and must be connected to a ground conductor with an earthing wire. It's also commonly used as an antistatic device to prevent damage to equipment. • Metal earth clamp• Maximum wire cross-section area of 10 mm²• Minimum diameter of 12 mm• Maximum diameter of 32 mm• Supplied with an aluminium label embossed with "Safety Electrical Connection Do Not Remove"• Meets ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 Electrostatic Control Standards• RoHS (Restriction of Hazardous Substances) Compliant
