1-way Protection Contact Socket OBO bettermann STD-D3S MZGN1 33° for Lightning/Surge Systems

Socket OBO bettermann STD-D3S MZGN1 33° is a 1-way protection contact intended for integration into lightning protection and surge arrestor systems. The component provides a single protective contact mounted at a 33° orientation and is designed to work within OBO bettermann installations to ensure a secure electrical connection between surge protection devices and earthing conductors. It is suitable for indoor and protected outdoor electrical enclosures where reliable contact geometry and mechanical stability are required.

Advantages

The 1-way protection contact offers a compact design with a precise 33° contact angle that simplifies alignment and installation in modular surge protection assemblies. Made to match OBO system interfaces, it provides consistent contact pressure and mechanical retention for long-term operation. The contact supports safe current discharge paths and helps maintain connection integrity under normal and fault conditions.

Suitable for

• Lightning protection and surge arrester installations
• Integration into OBO bettermann modular housings and connection systems
• Earthing and bonding connections in building electrical installations
• Industrial panels where a single directional protection contact is required

Key specifications

• Type: 1-way protection contact with fixed 33° orientation
• Compatibility: designed for use with OBO bettermann surge and lightning protection systems
• Function: provides a single protective contact for connection to earthing or surge conductors
• Mounting: suitable for integration into modular protection housings or panels
• Construction: mechanical contact geometry optimized for stable electrical connection

How to use

Install the protection contact into the designated slot or interface within the OBO modular housing or compatible mounting frame ensuring the 33° orientation aligns with the mating component. Make the electrical connection using the appropriate conductor size and fastening torque as specified by the overall system documentation. Verify mechanical retention and contact pressure after installation and perform continuity and earth resistance checks as part of commissioning to confirm correct operation.

Usage recommendations

Use this protection contact only as part of a complete lightning protection or surge arrestor system. Follow the system manufacturer's installation instructions and local electrical codes. Inspect connections periodically and replace the contact if signs of corrosion, wear, or loss of contact pressure are observed.
