High-Voltage Power Distribution: OBO 25 mm² Series Connectors
Secure ultra-heavy-gauge power lines with an elite 12-pole terminal strip engineered for massive electrical loads and extreme voltage thresholds.
The OBO 25 mm² Series Connector Strip (Part No. 2056577) represents the pinnacle of OBO's standard terminal range, purposely designed to tackle massive wire cross-sections and heavy-current circuits. Molded from premium, white halogen-free polypropylene, this ultra-rugged 12-pole strip is rated for operating levels up to 750V, making it the definitive choice for main power feeds and heavy industrial infrastructure layouts.
Key Specifications and Benefits:
- Massive 25 mm² Core Capacity: Dimensioned specifically to accept heavy-duty power lines up to 25 mm², eliminating connection bottlenecks and ensuring ultra-low resistance across critical junction networks.
- 750V Industrial Voltage Rating: Upgraded insulation metrics allow this terminal line to safely support higher-voltage sub-stations and large motor control links.
- High-Tensile Dual-Screw Clamping: Outfitted with high-purity brass inner blocks and heavy-duty grounding screws that exert massive mechanical torque to lock heavy conductors firmly in place against vibration.
- Toolless Sectional Separation: The specialized resilient polymer body allows contractors to cleanly twist and snap off custom lengths or single poles to match exact spatial constraints without a saw.
- Halogen-Free Safety Profile: Manufactured using top-tier, self-extinguishing polymers that do not release dangerous, corrosive gases or dense smoke during structural faults, satisfying rigid modern building targets.
Professional Installation Standards:
The 25 mm² OBO connector strip is the professional solution for industrial plant fit-outs, commercial sub-distribution networks, heavy ventilation feeds, and green energy arrays. By delivering outstanding dielectric strength, uncompromising mechanical gripping force, and an easily adaptable layout, OBO provides unyielding connection stability within major junction enclosures or switchgear cabinets alike.
