The XA-539796G-J is a 250A expansion section for Safe-Lec 2 conductor bar systems, engineered for medium-duty (MDM) heat-rated environments. It features a green PVC cover for visual phase identification and protection, and supports up to 0.06 Ohm resistance, allowing controlled expansion under variable thermal conditions. This section ensures stable electrical connectivity and mechanical alignment across long conductor runs, making it suitable for use in overhead cranes, monorails, and automated material handling systems where fluctuating temperatures are common. Key Features 250A current rating for industrial power applications Medium-duty (MDM) heat-rated design 0.06 Ohm resistance for consistent conductivity Green PVC cover for UV protection and phase marking Supports thermal expansion/contraction Compatible with Safe-Lec 2 conductor bar systems Ideal for crane electrification and mobile power systems
