The XA-539718-J is a specialized expansion section designed for 100A conductor bar systems that require thermal management. Featuring a medium heat rating and integrated heating elements with a resistance of 0.027 ohms, this section helps prevent condensation and freezing inside the conductor bar housing in cold environments. It supports thermal expansion and contraction, reducing mechanical stress while maintaining system reliability and continuous electrical conductivity. Ideal for industrial power distribution applications exposed to varying temperatures. Key Features Designed for 100A conductor bar systems Medium heat rating with integrated heating element Resistance: 0.027 ohms to prevent condensation and freezing Supports thermal expansion and contraction Enhances reliability in cold or variable temperature environments Maintains continuous electrical conductivity
