When it comes to building reliable power distribution systems, every connection matters. The TBB Series main branch connectors are engineered to deliver both efficiency and safety, providing the perfect solution for connecting main supply conductors across industrial and electrical applications.

Engineered Brass Design for Cost Efficiency

At the heart of the TBB Series lies a precision-engineered brass body. This advanced design not only ensures superior electrical conductivity but also reduces overall material costs, making it a cost-effective choice for manufacturers and installers. The simplified screw-mounting system allows for faster, cleaner installations—minimizing assembly time without compromising reliability.

Triple-Coated for Superior Compatibility

One of the key advantages of the TBB Series is its specialized triple coating on the brass surface. This innovation enables seamless compatibility with solid, stranded, and flexible conductors—whether they are copper or aluminum. The coating ensures corrosion resistance and prevents galvanic reactions, extending the connector’s service life even in demanding environments.

Safety Comes First

Electrical safety is non-negotiable. The halogen-free, self-extinguishing plastic casing used in the TBB Series provides enhanced fire resistance and thermal stability. This makes it ideal for use in modern electrical panels, where both safety and compactness are key design factors.

Additionally, the identical design of the 25 mm² and 35 mm² variants allows for easy stacking and modular combinations, ensuring flexibility in system configurations. Installers can mix and match according to project needs—simplifying design and inventory management.

Optimized for Modern Power Systems

With its compact structure, superior material engineering, and universal conductor compatibility, the TBB Series is perfectly suited for:

⚡ Main power distribution systems
🏭 Industrial panels and machinery
🔋 Energy and utility installations
🧩 Automation and control cabinets

Every detail—from screw geometry to insulation housing—is designed to streamline the connection process while maintaining maximum electrical integrity.

The TBB Series main branch connectors bring together efficiency, safety, and adaptability in one robust product line. Whether you’re working on an industrial control system or a renewable energy application, TBB delivers trusted performance and faster installation—helping you build smarter and safer electrical infrastructures.
