TERMINAL BLOCKS / BARRIER STRIP

25A Terminal Block — 5 Positions (Barrier Type)

TB-2505 provides 5 independent screw terminal connection pairs in a compact barrier-type layout, rated 25A / 600V. Each pair forms a point-to-point junction — there is no internal common bus between adjacent pairs. The ABS insulating body carries two rows of M4 wire-binding screws that accept solid or stranded copper wire (0.5 – 2.5 mm2 / 20 – 12 AWG). A transparent PVC dust cover (79.38 x 29.9 x 16.7 mm overall) protects the connection area while leaving terminations visible for inspection. Designed for organizing field wiring, control circuits, and auxiliary connections in industrial panels, machinery, and mobile electrical systems.

Product Details

  • 01 Barrier-type screw terminal interface — 5 independent pairs
    Each of the 5 pairs consists of two M4 wire-binding screws connected by a copper conductor. Adjacent pairs share a common insulating barrier and are not electrically connected. Accepts solid or stranded copper wire (0.5 – 2.5 mm2 / 20 – 12 AWG) — strip, insert, and tighten to 1.5 – 1.8 Nm.
  • 02 ABS insulating body with transparent PVC cover
    Body molded from ABS. Transparent PVC cover (79.38 x 29.9 x 16.7 mm overall) fits over the terminal area to help reduce accidental contact with live terminals while keeping terminations visible for inspection.
  • 03 Panel-mount design with 68.68 mm mounting pitch
    Two reinforced mounting flanges with 68.68 mm hole spacing allow screw-fastening to a suitable flat surface (panel, chassis, or equipment board). Overall footprint: 79.38 x 29.9 x 16.7 mm. Numbered position markers assist wiring identification.

Typical wiring applications

Point-to-Point Wire Termination

Routed as field-wiring terminations inside control panels, junction boxes, and machinery where each screw pair serves a separate circuit leg without bridging.

Control-Panel Circuit Interconnection

5 independent connection points for organizing relay coil wiring, sensor returns, pilot-light circuits, and auxiliary contact wiring inside industrial enclosures.

Harness-to-Panel Connection

Serve as the transition point between cable harness assemblies and fixed equipment wiring in mobile electrical systems (marine helm, RV battery compartments, off-road vehicle dash panels) and stationary automation racks.

Application examples describe common installation contexts. Verify the rated voltage, current, temperature, and environmental conditions match your specific application.
