What is the Difference between Disconnecting Panel and Load Break Switch?

 

[JG2828]

Wikipedia does a pretty good job at defining the difference:

Unlike load switches and circuit breakers, disconnectors lack a mechanism for suppression of electric arcs, which occurs when conductors carrying high currents are electrically interrupted. Thus, they are off-load devices, with very low breaking capacity, intended to be opened only after current has been interrupted by some other control device.

 

[RRaghunath]

Load break switches mean what the name implies - can break load current (with a power factor near to unity) but not fault current that could be thousands of amperes and the power factor is also likely to be poor.
