Grounding clamp Rittal SZ 2367.120, steel, silver, for earthing conductors (size 12mm)

Rittal SZ 2367.120 is a steel grounding clamp with a silver zinc-coated finish, made to connect and secure earthing conductors with a nominal 12 mm cross-section to enclosures, frames or structural parts. The clamp provides a stable mechanical connection and a low-resistance electrical path for cabinet and switchgear earthing tasks in industrial and commercial installations.

Advantages

The steel construction with a corrosion-resistant zinc coating ensures mechanical strength and long-term electrical contact. Its size and clamping design facilitate quick installation of 12 mm earthing conductors and maintain a firm, vibration-resistant connection. The simple shape and durable material make the clamp suitable for repeated use or retrofit grounding points on metal enclosures.

Suitable for

• Connecting 12 mm earthing conductors to electrical enclosures and cabinet frames
• Grounding points on switchgear and distribution panels
• Industrial installations where secure mechanical and electrical bonding is required
• Retrofit or maintenance grounding on metal structures and panels

When it may not be suitable

This grounding clamp is intended for 12 mm earthing conductors; it may not provide a reliable fit or required contact area for significantly larger or smaller conductor sizes. It is designed for use on metal surfaces and will not serve as an insulator or connector for non-conductive mounting substrates. For environments requiring stainless steel or special corrosion resistance beyond zinc coating, a different material specification should be chosen.

Key specifications

• Material: steel with zinc-coated (silver) finish
• Intended conductor size: 12 mm
• Application: earthing/grounding connection to enclosures and structural parts
• Mechanical function: clamp-style fastener for secure electrical contact

How to use

Position the clamp on the clean metal surface of the enclosure or frame where the earthing connection is required. Insert the 12 mm earthing conductor into the clamp and tighten the securing screw or fastener until a firm mechanical contact is achieved. Ensure any paint, corrosion or insulation is removed at the contact point to obtain a low-resistance electrical path. Verify the connection integrity with appropriate testing equipment after installation.

What to consider before purchase

• Confirm the conductor cross-section is 12 mm to ensure proper fit
• Verify the mounting surface is conductive metal and can be prepared for good contact
• Assess environmental conditions to determine if zinc coating corrosion resistance is sufficient
• Check mechanical fastening method compatibility with your enclosure or frame

Usage recommendations

For reliable grounding, always prepare mating surfaces by removing paint, oxidation or debris and use appropriate torque on fasteners. After installation, perform continuity and resistance checks to confirm a proper earthing connection in accordance with applicable electrical standards.
