Arc:

by | Mar 14, 2021

Gaseous electrical discharge between separated contacts of a switch, involving a stream of electrons, metal vapors and ions.

Capacity:

by | Mar 14, 2021

Usually refers to the current handling capability of a switch.

Arcing:

by | Mar 14, 2021

The flow of electric current between switch contacts during opening or closing of the contacts. This current flow can be damaging to the contacts of a switch.

Capacitive load:

by | Mar 14, 2021

A load in which the initial current on making (closing) of the contacts is higher than the steady state current. Current leads voltage in capacitive loads. See Resistive Load, Inductive Load, Power Factor, Inrush.

AWG:
