The OTB4000/6 is a high-performance phase separator barrier plate engineered for extra-large low-voltage switch technology. It acts as a safety partition wall installed between electrical poles to maximize air insulation and prevent arcing or short circuits across high-current phases. Designed primarily for industrial power distribution, HVAC, and data center installations, these barriers maintain safety compliance without requiring a complete terminal shroud system.
