10 Pole 2 Row Terminal Strip

This barrier terminal strip provides ten poles across two rows for industrial power distribution. It accepts wire from 22 AWG up to 12 AWG and is rated for 20 A at 300 V AC. The phenolic housing measures 5.18 in long by 1.12 in wide and 0.59 in high. It suits control panels and machinery wiring that need secure screw connections.

Replaces loose wire junctions

The strip replaces ad hoc splices or smaller blocks when a project demands ten circuits in a compact footprint. The jump is worth it when installers need a single black phenolic block with 7/16 in center spacing instead of multiple discrete connectors. It is not for buyers who require an integrated cover or a different pole count.

Sustained 20 A load behavior

Under continuous 20 A load the phenolic housing and screw terminals maintain rated voltage without hot spots. The 12 AWG maximum wire gauge ensures adequate copper cross-section for prolonged current flow. No cover is included so heat can dissipate freely in ventilated enclosures.

Questions about this item

What mounting holes or spacing does this 10-pole terminal strip require?

The strip measures 5.18 in overall length, 1.12 in width and 0.59 in height with a 7/16 in center spacing between poles, so allow that footprint when drilling or DIN-rail planning.

How do I wire the 12 AWG conductors into the screw terminals without damaging the phenolic housing?

Strip each wire to the recommended length, insert fully into the barrier terminals, and tighten the screws to a firm hand-torque — over-tightening cracks the black phenolic housing.

When should I expect to replace this 20 A, 300 V terminal strip?

Inspect annually for discoloured phenolic, loose screw terminals or corroded contacts; replace the strip if any pole shows heat damage or fails a continuity check at 20 A.
