Distribution Blocks

Screw-Clamp Terminals

Stud Terminals

With the help of distribution blocks, you can take a large wire from your power source and connect it to one or more wires going to your electrical devices.

Blocks with screw-clamp terminals have a current rating based on NEC table 310-16 using 75° C copper wire.

Covers protect the top of the block and prevent accidental contact with live circuits.

DIN-Rail Mount Distribution Blocks

Mount to DIN rail for quick installation and removal. These distribution blocks take a high-current wire from your power source and connect it to one or more wires going to your electrical devices.

The current rating is based on NEC table 310-16 using 75° C copper wire.

Blocks with a quick-disconnect load connection allow you to connect an auxiliary device, such as a horn or light.

Blocks that meet IP20 protect connections from objects larger than 12.5 mm, such as fingers.

One Circuit with Stud and Screw Terminals

Two Circuits with Stud and Screw Terminals

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.

Covers protect the top of the bar and prevent accidental contact with live circuits.
