The XA-539846-J is a 315 amp expansion section engineered for Safe-Lec 2 conductor bar systems. It features a built-in heating element rated for medium heat output with a resistance of 0.06 ohms. This expansion section allows for the safe compensation of thermal expansion and contraction within the conductor bar assembly, maintaining consistent electrical connectivity. The heating functionality prevents condensation buildup, which could otherwise cause corrosion or electrical faults, thereby enhancing system reliability and durability in industrial applications such as cranes, hoists, and automated material handling systems. Key Features Rated for 315 amps current capacity Heated expansion section with medium heat output Resistance: 0.06 ohms Compatible with Safe-Lec 2 conductor bar systems Prevents condensation and moisture formation Compensates for thermal expansion and contraction Enhances operational reliability in demanding environments
