Overview
The 5566137 terminal strip is a rugged industrial terminal block engineered for multi-wire connections in control panels, electrical enclosures, and distribution systems. With 8 poles and a 30A current rating at 600V AC/DC, this terminal strip handles demanding applications in manufacturing, industrial automation, and facilities maintenance. The screw-clamp design ensures reliable, repeatable terminations without specialized tools.
