StuvEx Safe-Ground CMS1 Stainless Steel Clamp for Hazardous Areas & Explosion Protection
The Safe-Ground CMS1 stainless steel earthing clamp with ATEX Certification designed to provide an effective, low-resistance connection between movable objects and earth to safely dissipate any static electricity. The stainless steel earthing clamp is suitable for use in hazardous areas and forms part of the StuvEx static earthing product range.
The Safe-Ground CMS1 earthing clamp is spring-loaded and equipped with hardened, sharp teeth. When the ATEX earthing clamp is applied to the object, the teeth immediately penetrate paint, rust or dirt, resulting in a connection resistance of less than 10 Ohm according to IEC/TS60079-32-1:2013/A1:2017.
The Safe-Ground CMS1’s robust design, integrated strain relief and high-quality material make the clamp ideal for use in harsh working conditions and in petrochemical, off-shore and other process industries.
➡ Thorne & Derrick together with StuvEx supply Static Bonding Clamps, Cables & Connectors to the hazardous area EX industries with over 35 years experience.
