Overview

The ABB L400H Type L copper terminal block is a heavy-duty, one-hole mount connector engineered for high-current industrial applications. Designed to handle conductor sizes from 4/0 AWG stranded to 500 kcmil, this terminal block delivers reliable performance in power distribution, motor control, and switchgear systems where robust terminations are critical. The L400H features a hex head screw for secure, vibration-resistant connections, minimizing maintenance and downtime in harsh operating environments. Measuring 3 inches in length with a width of 1-13/32 inches and a height of 1-15/32 inches, the L400H fits standard enclosures and DIN rail configurations. Constructed from high-conductivity copper, it ensures low-resistance pathways for consistent electrical performance. The one-hole mount design simplifies installation while providing a stable, long-lasting termination point for large conductors. The hex head screw allows for tool-based tightening, ensuring precise torque control for optimal electrical contact and mechanical stability. The terminal block’s compact dimensions (3" L x 1-13/32" W x 1-15/32" H) make it suitable for space-constrained installations while maintaining compatibility with standard mounting hardware. Its copper construction provides superior corrosion resistance and thermal conductivity, reducing heat buildup in high-current applications. The L400H is specifically designed for use with copper conductors only, ensuring compatibility with industry-standard wiring practices. This terminal block is ideal for applications requiring durable, high-current connections, such as industrial machinery, renewable energy systems, and utility power distribution networks. The one-hole design allows for quick and efficient installation, reducing labor time and potential errors during wiring. The terminal block’s robust construction ensures long-term reliability, even in environments with high vibration or temperature fluctuations.
