Product Description:

This controller enclosure measures 12'' x 10'' x 8" (300 x 250 x 200 mm).  Two 1/16 DIN sized controllers can be installed with adequate room for wiring and switching device. A optional two pre-cut holes for 1/16 DIN controller are offered for this box. 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 a heat sink. The door comes with a 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 wholes 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. Grounding lugs with M6 thread are located on the inner side of both the front cover and the body of the box.  
The box has a pre-cut hole on the top for external heatsink. 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. Three different sizes of heat sink are offered: 40 A, 60A, and 75A.  All three heat sink come with pre-drilled and tapped mounting holes for the box and SSR. The 60A and 75A heat sinks have mounting holes for two SSRs. Mounting screws and thermal conductive grease are included. There is no need to cut for installing the heat sink. Please select the heat sink size option when ordering. 

Now factory precut (two controller holes, please check pictures below) is offered.
Note: Scratch & Dent box are available for limited models. Please check here.
