Product Description
Application Description
An Air Conditioning Disconnect (ACD) is a disconnect located between a loadcenter (distribution panel) and air conditioner. The Cutler-Hammer ACD by Eaton Corporation provides an installer or repair personnel with a visible disconnecting means when performing maintenance. ACDs are also known as disconnects, pullouts or air conditioning switches.
Non-fused pullout and molded case switch devices provide personnel with a visible on-off disconnecting means. While fused pullout units also perform this function, they also provide an additional level of protection for the air conditioner.
Molded Case Switch
Non-Fused Pullouts
7
Fused and non-fused devices are of a pullout design, where the user physically removes or “pulls out” a tab to break the electrical connection. A molded case switch is similar to a light switch where the user “switches” the unit to the indicated ON-OFF position.
DPB222R ■
Rugged molded case construction in a disconnect switch that looks like a circuit breaker but operates like an ordinary household light switch. ■ Plug-in molded case switch eliminates the need for pullout handles. ■ No need for replacement pullout handles due to loss or theft. ■ Includes non-automatic molded case switch.
Note: Most applications involving water require a ground fault breaker.
The most widely used application is for residential and light commercial air conditioning units. An ACD is installed outdoors, in a visible range from the air conditioner. ACDs are also found in use with heat pumps, swimming pools, spas, whirlpools and pump houses. Metallic enclosures are galvanized steel and are installed in various locations. Non-metallic enclosures are a plastic (polycarbonate) enclosure commonly used in coastal or saltwater areas.
Fused Pullouts
DPU222R ■
ON/OFF control provided by a pullout handle. ■ Pullout handle can be conveniently stored in the compartment in the OFF position, helping to prevent the handle from being misplaced. ■ Protective shield cannot be removed until the pullout handle is removed, disconnecting the power.

Fuses are installed behind the protective shield that cannot be removed until the pullout handle is removed, disconnecting the power. ■ Horsepower ratings apply when time delay fuses are used. Class H fuse clips are provided. Fuses not included. ■ ON/OFF control provided by a pullout handle. ■ Pullout handle can be conveniently stored in the compartment in the OFF position, helping to prevent the handle from being misplaced.
