The Delta CA Series handles the small surges, like harmful voltage spikes up to 6000 volts, protecting delicate electronic devices. While it is not possible to achieve one hundred percent protection, Delta units will greatly reduce problems due to lightning, power surges, and spikes. Using both units will protect against both high and low energy surges.
A surge capacitor is a device designed to absorb surges and/or reduce the steepness of their wave front. A capacitor is able to absorb and hold a charge of electricity, returning it to the circuit at a later time. Since the surge capacitor is always connected to the power circuit, current flows at all times. When a surge occurs, added current flows to the capacitor thereby lowering the intensity of the surge voltage. The amount of current the capacitor can absorb depends on the size of the capacitor, and the amount of voltage pushing the current.
If the surge is of a low current relative to its voltage intensity, the capacitor will absorb it. If the surge has high current, the capacitor cannot absorb it.
By contrast, the Delta lightning arrestor takes no current from the line during normal operation. When a surge occurs, the arrestor turns on to provide a discharge path. When the surge is gone, the arrestor turns off. The arrestor will handle unlimited amount of current, although amounts exceeding 100,000 amps will generally damage the arrestor.
The main advantage of a capacitor is that there is no time delay in turning on as it always conducts. The disadvantage is that the amount of current it can handle is limited to a few amps, depending on the surge voltage. For this reason, an arrestor should always be installed with a capacitor to protect it from intense surges.
This unit is designed for light duty service such as single phase commercial and residential entrance panels. An internal automatic discharge circuit is provided.
