The HWHK Series, from Hammond Manufacturing, is a family of easy to open, yet secure, wall mount enclosures designed to house electrical and/or electronic equipment in harsh industrial environments. Available as standard in 30 sizes in six heights from 24 to 60 in., five widths from 16 to 36 in. and five depths from 6 to 16 in., the range is specifically engineered for use in heavy industrial plants, utility, outdoor municipal or other locations where the enclosure sits in harsh conditions and is frequently opened for internal equipment access.
Access is through a durable zinc die-cast handle with padlock provision, which operates a smooth action three-point roller latch locking system that gives excellent sealing with minimum effort in opening and closing the door. The rugged full height stainless steel piano hinge enables 180° door opening, and the removable hinge pin allows the door to be demounted if required.
Manufactured from 14 gauge mild steel, finished with a recoatable smooth ANSI 61 gray powder coating to both the interior and exterior, the HWHK features ground smooth continuously welded seams, a formed lip to exclude flowing liquids and contaminants and a seamless poured-in place gasket. It meets the requirements of UL 508 Type 3R, 4 and 12, CSA Type 3R, 4 and 12, NEMA 3R, 4, 12 and 13 and IP66 to IEC 60529.
A comprehensive range of standard accessories enable the units to be configured to suit almost any application: a removable inner mounting panel, gland plates, passive or active thermal management, drip shields, windows and grounding kits are all available. For application-specific requirements that cannot be satisfied from the standard range, modified versions are available on short delivery times.
