The 130-D is a crossbar component used within the 130 Series compression clamp assemblies for mounting high-power disc semiconductors up to 2.25 inches in diameter. This crossbar provides a device mounting space, defined by its 'X' dimension, ranging from 2.67 inches (67.8 mm) to 3.05 inches (77.5 mm). When paired with a compatible 130 Series spring assembly, it facilitates a clamping force between 800 and 2,000 lbs. These clamp systems are crucial for proper installation and thermal management in power distribution equipment, industrial controls, and power conversion systems.
