The XA-539761-J is a 125A expansion section built for conductor bar systems exposed to medium heat conditions. Featuring high-temperature-resistant (HTR) materials, this expansion section is engineered to absorb thermal expansion and contraction, helping to maintain conductor alignment and reduce mechanical stress. It delivers a resistance of 0.15 Ohm, providing consistent and reliable current flow across the system. This product is ideal for industrial applications where conductor systems must remain stable and functional under fluctuating thermal loads. Key Features Rated for 125A conductor bar systems HTR medium heat-resistant construction for elevated temperature environments Resistance: 0.15 Ohm Supports thermal expansion/contraction Maintains conductor alignment and reduces wear Designed for reliable long-term electrical continuity Suitable for industrial and commercial power distribution systems
