Wall Mount Box for Three Controllers 16x12x8"

This controller enclosure measures 16 x12 x 8" (400 x 300 x 200 mm). Three 1/16 DIN sized controllers or timers can be installed with adequate room for wiring and switching device. The box is made of powder coated, 0.040" (1 mm) thick steel. One side of the wall has a pre-cut opening. It can be used for installing cables or heat sink. The door comes with lock and key. The hinge of the door are removable. It can be installed on either right or left side. This allows the user put the pre-cut opening either on top or at the bottom without changing the door opening directions.  Gasket and plugs are provided. It is rated for IP65 before any holes are cut. The enclosure is designed to be mounted on a wall. You can directly mount it with screws or hang it on the wall with the optional hangers. For high power circuit, wall mount box is preferred because the heavy cords (14 AWG or thicker) are difficult to manage with a table top enclosure. 

The box has a pre-cut hole on the top for external heat sink. If you are going to use SSR instead of contactor as the switching device, you can order the optional external mounted heat sink. The external mounted heat sink eliminates the venting requirement of the enclosure for internally mounted heat sink. It is more efficient and keeps the internal of the controller box free from the dust. The heat sink can dissipate heat generated  by 75 ampere of current passing through the SSR.  The heat sink come with pre-drilled and tapped mounting holes for the box and SSR. Mounting screws and thermal conductive grease are included. There is no need to cut for installing the heat sink. 

An option of three factory knockout holes for 1/16 DIN controller is offered. It will save a lot of time and effort for most users that don't have the tools/machinery to cut it. User needs to cut some round holes for switches and connectors. But round shaped holes are much easier to cut on the sheet metal than square holes. Three knockout holes are set equal intervally on the same horizontal level. Customers can remove those knockout holes as needed. The distance from top of hole to the top of enclosure is 114.5mm (4.51"). The distance from left of hole to the left of enclosure is 47mm (1.85").

Optional DIN Rail set is offered. It includes one piece of DIN Rail, one pair of DIN Rail end caps and one set of mounting screws & nuts.
