What is a Terminal Block? Introduction Terminal blocks are used for the space-saving connection of incoming and outgoing conductors in control systems. They are an insulating part carrying one or more mutually insulated terminal assemblies and intended to be mounted to a support. They are designed for solid, stranded and finely stranded conductors with or without end sleeves.

Through-Type Terminals (a.k.a. Feed-Through) Wire Entry Common Conduction Path Wire Clamping Points Through-Type terminals get their name because there is a common conduction path between wire clamping points. Selection

Common Conduction Path Two-Tier Terminals (a.k.a. Feed-through, Multi-Circuit, Multi-Level) Wire Entry Common Conduction Path Wire Clamping Points Two-Tier (a.k.a. Double Tier) terminal blocks can save up to 50% of the width required to standard Through-Type terminal blocks with one conducting path. Two-Pole designs are isolated so one current path could be AC and the other current path could be DC. Single-Pole terminals allow 4 wire terminations to a single point. Selection

Ground (PE) Terminals (For Connection to a DIN Rail) Wire Entry Ground Path DIN Rail Metal Clamping Mechanism Ground terminal blocks provide electrical connection to a DIN rail that serves as a ground bus. This eliminates the need for a separate ground busbar and allows the ground terminals to be lined up with the insulated main conductor terminal and neutral isolating terminals in any required arrangement. Thus a clear relationship to the individual circuits can be established. The ground path is from the wire entry to the DIN rail via the metal clamping mechanism. The DIN rail is grounded to the metal panel or to a ground rod. Selection

Fuse Terminal Block Fuse Holder Fuse Wire Entry Fuse Terminals are used to protect control circuits from short circuits. They are intended for G fuse links (5 x 20 mm or 5 x 25 mm) up to 6.3 Amps, 250 V; and, for bridging links up to 16 A, 500 V. Selection

Terminal Block Density Terminal Block Density is based on the Width of the Terminal Block over a Linear Measurement. The Linear Measurement is usually expressed in the number of pieces per foot or meter. Example: 8WA1011-1DG11 is 6.5 mm Wide. How many terminal blocks can we get into A) one foot and B) one meter. 1 inch = 25.4 mm; 12 inches = 304.8 mm Terminals per Foot = 304.8 / 6.5 = 46.89 = 46 1 meter = 1000 mm Terminals per Meter = 1000 / 6.5 = 153.85 = 153 Selection

Used at the end of a terminal block run where a physical barrier is required to prevent contact with electrical Parts. Small Partition (a.k.a. Separator) – Used with Terminal Sized 2.5 through 35 to provide electrical isolation between adjacent parallel links. Small Partitions do not increase the width of the terminal group and can be fitted after the terminal group is assembles. Cover with Warning Arrow – Assist in the identification of power input terminals and provides an additional physical protection against contact with live conductors. Blank white covers are also available for in-site inscription Barrier – Barriers are yellow in color and extend 5 mm beyond the contour of the terminal block. They are used to provide visual separation between terminal groups and electric al isolation between adjacent parallel link groups. A knockout is provided to allow the use of a neutral busbar when required.
