DIN rail and channel terminal blocks are rack or box mount connection points for securing two or more wires to a circuit or power bus. ... UL certified and IEC rated terminal blocks are selectable by current and voltage parameters as well as wire gauge, body color, and termination style.
What does DIN stand for in DIN rail?
Deutsche Institut fur Normung
Why is it called DIN rail?
The name DIN-Rail was based on the DIN (Deutsche Industrie Norm) (translation: German Industrial Standard) which defined the dimensions and tolerances of the rail in order to allow manufacturers to design mounting and assembly methods for products destined for assembly onto the rail.
What is bus bar used for?
A busbar is an electrical junction used for collecting electric power from the incoming feeders and distributes them to the outgoing feeders. The main purpose of a busbar is to carry electricity and distribute it. Busbars are used to make the systems more efficient.May 17, 2021
What is a bus bar in an electrical panel?
Bus bars are metal bars inside an electrical panel that carry electrical current and hold the circuit breakers. Other electrical panels have a single bus bar that runs the length of the electrical panel. A split bus panel will have a large breaker on the top bus bar that feeds power to the lower bus bar.Jul 26, 2021
What is a busbar in a consumer unit?
Busbar - A copper 'comb toothed' bar which electrically connects the 'circuit devices' to the 'isolation devices'. The busbar is cut to size by the electrician, when installing the consumer unit and 'plugs in' to the bottom of all devices.
What is distribution system define busbar?
In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution.
What is the function of a busbar?
Busbars are metal bars used to carry large amounts of current. Often made of copper or aluminum, every home electrical panel has busbars to distribute ac power to the rows of circuit breakers (Fig.Jan 15, 2020
What makes busbar special?
Bus bars reduce system costs, improve reliability, increase capacitance, and eliminate wiring errors. They also lower inductance and increase capacitance. Plus, the physical structure of bus bars offers unique features in mechanical design.
What is the difference between bus and busbar?
is that busbar is an electrical conductor that carries a large current, especially one that is part of a power distribution system ; typically a thick strip, or a tube, of copper or aluminium while bus is (automotive) a motor vehicle for transporting large numbers of people along roads.
How do I choose a busbar size?

The IEEE states a busbar should be rated at the highest amperage passing through any section of the busbar, with a maximum of a 50° C rise in temperature from an ambient temperature of 50° C. ... This rating method avoids excess terminal temperature at the wire termination.Oct 16, 2014
