The Internorm style desktop system is the innovative enclosure solution for the 19 range. All space-optimised versions are based on the Interzoll module mounting rack program and represent excellent value for money. Different front elements give the Internorm style an individual and functional design. The enclosure type with integrated ventilation ( 2x 1/2 HE ) ensures increased heat dissipation; the exterior is 1 HE higher. All standards designs offer good EMC screening, which can be increased by the use of additional components.
