Non-fused Switch: To be used a means of isolating the power source from the control panel. This method can be used if there is a source of circuit protection located prior to the non-fused switch.

Fused Switch: To be used a means of isolating the power source from the control panel. This method can be used if there is no source of circuit protection located prior to the fused switch. If an overload condition occurs, the fuses with open and isolate power. The fuses will need to be replaced after the overload condition has been corrected.

Breaker: To be used a means of isolating the power source from the control panel. This method is the same as the fused switch, however in the event of an overload condition the breaker will trip and isolate power. Once the overload condition has been corrected, the breaker can be reset.

The breaker is more expensive initially but over the life of the control panel may be less expensive. Depending on the breaker size, replacing the fuses 2 to 5 times will equate to the cost of the breaker.
