Product Description:
On the 3TB170.91-02, there are a total of twenty pins. Regard this item to be used as a push-in terminal block, only copper line wires are applicable. This implies that it is suitable for use within various industrial applications because it meets nominal data features of UL standard along with its pitch measures as 5.08 mm.
The terminal blocks wide range of cross-sectional areas can accept different thicknesses of cables in its design. This is because its current-carrying capacity covers wire gauges from size 26 to size 12 AWG. Similarly, this means that single wires should have diameters starting from ranges such as 0.20 up to 2.50 mm^2; fine-stranded wires whose diameters also fall under the above range and end sleeves (with or without plastic covering) having ranges between 0.20 and 1.50 mm^2.
The nominal voltage rating on the terminal block is V300 and it houses a current load per contact not exceeding 10 A according to the catalog page where they are specified among other electrical characteristics integrated into the actual terminal blocks themselves. This limits contact resistance 2^5 milliamperes so that creating solid electrical connections does not result in any power loss during their formation process. Hence specifically indicates this component operates like an intermediate connection thereby enabling one point in an industrial control systems wiring diagram.
