1447A SINGLE DOOR DISCONNECT ENCLOSURES - NEMA 12, 13
Allen Bradley, 1494 F & D Series Only

Application

  • Designed to house Allen Bradley 1494F flange mounted disconnect switches and 1494D flange mounted circuit breaker operators (will not accept Allen Bradley 1494V disconnect switches).
  • Provides a degree of protection from falling dirt, dust, oil and water.

Standards

  • UL 508 Type 12, 13
  • CSA Type 12, 13
  • Complies with
    • NEMA Type 12 and 13
    • JIC EGP-1-1967
    • IEC 60529, IP54
    • Appropriate components are required to maintain these standards.

Construction

  • Formed 14-gauge steel.
  • Continuously welded seams.
  • Larger sizes include door and body stiffeners.
  • Welded brackets provide for enclosure mounting.
  • Formed lip on door and enclosure exclude flowing liquids and contaminants.
  • Cutouts and holes are provided to suit the handle, operating mechanism and door closing mechanism.
  • Continuously hinged doors may be removed by pulling the hinge pin.
  • Guide and cover interlock brackets are welded to the door.
  • Cover latch bars for door hardware are provided.
  • A spacer kit to support the disconnect on the panel is included.
  • Collar studs are provided for mounting inner panels.
  • A removable 12 gauge inner panel is included.
  • Oil resistant gaskets are permanently secured and mechanically retained.
  • A bonding stud is provided on the door and a grounding stud is provided in the enclosure.
  • A literature pocket is provided.

Note:

  • Disconnects, operating mechanisms, and door hardware are not provided with the enclosure, and must be ordered separately from the manufacturer.
  • Enclosures with an "A" dimension under 40" require 2 point door closing hardware. Order one Allen Bradley 1494F-L1.
  • Enclosures with an "A" dimension of 40" or more require a 3 point
    door closing mechanism. Order one Allen Bradley 1494F-L2 and one 1494F-L3.
  • Enclosures 1447A K122 and 1447A L122 accept a 200 A switch only. This switch will not fit in any other 1447A Series Enclosure. Order Allen Bradley 1494F-L4 door hardware for 1447A K122 and 1447A L122 enclosures.

Finish

  • Door and enclosure are phosphatized and finished in ANSI 61 gray recoatable powder coating on the outside.
  • Enclosure interior is finished in white powder coating.
  • Inner panel is finished in white powder coating.

Space Occupied by Disconnect
Note: "K" = 3.84 when "C" = 8.00
"K" = 6.75 when "C" = 10.00
"K" = 9.50 when "C" = 12.00
(except enclosures for 200A switches)
"K" = 9.50 when "C" = 16.00
"K" = 10.50 when "C" = 12.00
(for enclosures with 200A switches)
"P" = Wiring Space
Disconnects will occupy space on panel shown by dimensions "K", "L" and "M".
Wiring space "P" is available when disconnect is installed in the enclosure.
*The disconnect information and space occupied tables based on data supplied by disconnect manufacturer’s bulletins. Hammond Manufacturing is not responsible for dimensional accuracy.
