jaotuslüliti

A jaotuslüliti, also known as a distribution switch or changeover switch, is an electrical device used to connect a load to one of two power sources. It is typically employed in situations where a primary power source, such as the main utility grid, is supplemented by a backup source, like a generator or an uninterruptible power supply (UPS). The primary function of a jaotuslüliti is to ensure a seamless and safe transition between these power sources.

These switches are crucial for maintaining continuous power supply to critical equipment and systems, preventing disruptions during power outages or maintenance. They operate by physically or electrically isolating the load from one source and connecting it to the other. Manual jaotuslülitid require an operator to physically move a lever or turn a knob to select the desired power source. Automatic jaotuslülitid, on the other hand, can detect a failure in the primary source and automatically switch to the backup source without human intervention.

The selection of a jaotuslüliti depends on factors such as the required power rating, voltage, the type of power sources involved, and whether automatic or manual operation is desired. They are commonly found in residential buildings, commercial establishments, industrial facilities, and hospitals, where reliable power is essential. Proper installation and maintenance of a jaotuslüliti are vital for ensuring its effective operation and the safety of the electrical system.
