Controls for the reclosers range from the original electromechanical systems to digital electronics with metering and SCADA functions. The ratings of reclosers run from 2.4–38 kV for load currents from 10–1200 A and fault currents from 1–16 kA. [7] [8] On a 3-phase circuit, a recloser is more beneficial than three separate fuse cutouts.
These allow setting of the “sweep speed” (the rate which the door travels along the majority of its closure, the sole closing setting on basic closers); the “latch speed” (the rate in the last 10 to 15 degrees of closing arc, allowing it to be set faster than the "sweep" to ensure proper latch closure); “delayed action” (which slows ...
Rate of fire is the frequency at which a specific weapon can fire or launch its projectiles. This can be influenced by several factors, including operator training level, mechanical limitations, ammunition availability, and weapon condition.
While the recloser does in fact help to break up distribution circuits into smaller, more manageable pieces, many protection schemes involving circuit breakers in distribution substations also apply reclosing to some extent, thus not "blacking out" the circuit and requiring a crew go to the station and reset a lockout.

Reindeer can reach a running speed of almost 50 miles per hour(80 km), though most recorded speeds are between 25 and 35 miles per hour (40-56 km), which is still quite impressive.

A rather more cumbersome interrupter was constructed by the American Charles Page slightly earlier in 1838 but Bird's work was entirely independent. Although there is little in common between the two interrupter designs, Page takes the credit for being the first to use permanent magnets in an automatic interrupter circuit.
