Terminal Blocks

Terminal blocks are the foundational wiring components used by controls engineers, panel builders, and machine builders to organize, distribute, and secure field wiring within control enclosures and electrical panels. This category spans a broad range of block types, including feed-through terminal blocks for straightforward point-to-point conductor connections, ground terminal blocks that integrate a dedicated earth-ground circuit alongside a feed-through circuit, and two-level or multi-level terminal blocks that maximize wiring density in space-constrained panels. Accessories such as jumper bars, end anchors, and test plugs round out the selection for complete panel wiring solutions. Available in various wire acceptance sizes — from 1.5mm² signal wiring up to 4mm² and larger power conductors — and in color-coded variants to support IEC wiring standards, these components support DIN-rail terminal block panel layouts across process control, machine control, and industrial automation applications.
