Terminal Blocks: Learn About Terminal Blocks Here > Terminal Blocks (also known as connection terminals or screw terminals) are modular, insulated sections that fasten two or more wires together and consist of an insulating frame and a clamping
component. Often associated with DIN rails in either IEC or NEMA rating, their adjustability allows wiring to be centralized and makes it easier to manage complicated control circuits. Today's control
wiring solutions are gradually becoming more and more complex as equipment is constrained to smaller and smaller spaces, and industry calls
for more responsiveness and higher amounts of automation. Within the control board, these modular components are snapped firmly into place
on a mounting rail.
When modifications in the circuit must be carried out, terminal blocks can be easily added or removed from the rail without interfering
with other wire terminations. In addition to minimizing complexity of control wiring, the plastic frames of terminal blocks also protect
against shorts and subsequently provide increased safety to installers and service crews.
