Industrial-Grade Power Splicing: OBO 16 mm² Series Connectors
Secure maximum-diameter power paths with an ultra-heavy-duty 12-pole terminal strip engineered for heavy-current sub-distribution.
The OBO 16 mm² Series Connector Strip (Part No. 2056550) represents the heavy-current threshold of OBO's standard terminal family, engineered to safely manage large power conductors and high electrical loads. Molded from premium, white halogen-free polypropylene, this robust 12-pole strip easily manages operating thresholds up to 450V, providing structural insulation and secure connections for intensive commercial and industrial infrastructure.
Key Specifications and Benefits:
- Massive 16 mm² Cross-Section: Specially sized and rated to accept heavy-gauge solid, stranded, or flexible core conductors up to 16 mm², eliminating bottleneck resistance in high-load setups.
- Twist-and-Separate Layout: Formulated from high-grade polypropylene that allows individual poles or custom terminal lengths to be separated by hand without tools, maximizing installation adaptability.
- High-Tensile Brass Terminals: Features precision-engineered internal brass blocks with robust, dual-clamping screws per pole to apply heavy mechanical pressure and stop wire migration under industrial vibration.
- Halogen-Free Material Safety: Composed entirely of self-extinguishing polymers that minimize smoke density and eliminate toxic gases during an electrical fire, protecting critical building spaces.
- Superior Structural Insulation: Delivers high thermal stability and dielectric strength, ensuring the casing maintains its shape and performance parameters over extensive operational lifespans.
Professional Installation Standards:
The 16 mm² OBO connector strip is the professional benchmark for fast-paced commercial fit-outs, heavy HVAC control systems, industrial machine linkages, and main power feeds. By combining immense wire retention and superior current-carrying capacity with a practical, cut-to-length design, OBO ensures seamless, weather-secure splicing inside main junction boxes or control cabinets.
