Harsh-Environment High-Current Distribution Bars


Stud Terminals 1 Circuit	Stud and Screw Terminals 1 Circuit	Stud and Screw Terminals 2 Circuits

Protect connections against corrosion. These bars are tin-plated copper and have stainless steel terminals. Also known as bus bars, they serve as connection points between wires with ring or spade terminals. The underside is sealed, so the bars can be safely mounted to conductive surfaces.

Distribution Bar Covers—Distribution bar covers protect the top of the bar and prevent accidental contact with live circuits.

Distribution Posts

Stack multiple ring or spade terminals on the stud terminal; the current flows through the stacked terminals. The round design saves space.

Terminal Blocks for Motors

Rotate the jumpers on these blocks to match wye (Y-shaped), delta, and other wiring layouts on three-phase motors. Each jumper connects two terminals positioned side by side, across the block, or on a diagonal.

For a reliable connection, attach a terminal to your wire before installing. Ring, spade, and hook terminals fit around the stud and hang on tightly, even in high-vibration setups. Pin terminals, blade terminals, and wire ferrules are easier to fit into the block, but they don't stay put as well as other terminals when vibrated or pulled.

Terminal Blocks

Also known as barrier terminal strips, these blocks have dividers to separate live wires and keep your setup tidy. Mount them directly onto control panels, enclosures, and equipment.

A screw or stud connection creates a tight hold on the wire. You can insert stripped wire directly or attach a terminal to prevent damage from the fastener. Ring, spade, and hook terminals fit around the shank and hang on tightly, even in high-vibration setups. Pin terminals, blade terminals, and wire ferrules are easier to secure with the screw or stud. However, they don't stay put as well as other terminals when vibrated or pulled.

For DIN 3 Rails—Unlike other surface-mount terminal blocks, these have a notch that snaps onto DIN 3 rail. You can also screw them directly onto your control panel or other surface.

High-Current Distribution Posts

Distribute up to 150 amps from the center stud terminal to the eight screw terminals around it. The round design saves space.

Marine-Grade Battery Terminal Clamps

Made of lead, these clamps resist corrosion to stand up to marine-grade environments. Use a lug to attach your cable to the stud.
