The HJ643HLP is a 6 x 4 x 3 in (152 x 102 x 76 mm) Type 4 and Type 12 mild steel junction box from the HJ H Series, built with a continuous-hinge door held closed by clamps. Its compact footprint suits small terminal splices, instrument wiring and single-device control housings. It is designed for use as an instrument enclosure, an electric, hydraulic or pneumatic control housing, an electrical junction box or a terminal wiring enclosure.
The body is formed from 16 or 14 gauge steel and the cover from 14 gauge steel, with smooth, continuously welded seams and no knockouts, cutouts or holes, so you place entries exactly where your layout needs them. The door closes on a seamless poured-in-place gasket and is secured with stainless steel clamps and screws; its stainless steel continuous hinge can be removed by pulling the stainless steel hinge pin. The enclosure and cover are phosphatized and finished in recoatable smooth ANSI 61 gray powder coating.
The drawing shows a 6.31 x 4.31 in door, a 5.30 x 3.30 in door opening and 5.09 x 3.10 in of clear space available on the door. Welded brackets with 0.31 in mounting holes, spaced 6.75 in vertically and 2.00 in horizontally, give an overall mounted height of 7.50 in. Internal threaded weld studs accept the optional 14R0503 mounting panel, which measures 4.88 in (124 mm) x 2.88 in (73 mm); alternative inner panel options are also available. A bonding stud is provided on the door and a grounding stud inside the enclosure.
The HJ643HLP is listed to UL 508A Type 3R, 4, 12 and 13 (UL file E65324) and CSA Type 3R, 4, 12 and 13 (certificate LR21001), and complies with NEMA Type 3R, 4, 12 and 13 and IEC 60529 IP66. The series is intended for locations where equipment may be hosed down or otherwise be very wet, and for outdoor applications needing full weather protection. It is REACH and RoHS compliant and ships boxed at 2 lbs (0.91 kg).
