HARTING Han® HP Direct B Housing System features a gray powder surface with classic nitrile butadiene rubber (NBR) seal. The B system is a standard version that serves indoor industrial applications and replaces classical bulkhead mounted housing with two mounting flanges. The construction allows the standard hood to form a seal directly on the switch cabinet wall to save space. Installation only requires the user to screw the mounting flanges to the switch cabinet wall. HARTING Han HP Direct B Housing System is available in the classic sizes of 6B, 10B, 16B, and 24B. All sizes are available with side or top entry in sizes M20, M25, M32, and M40.
