The FORMAT Metal Door (article YKM40D-FO-DM-200-040) is a single-leaf, 2000 mm × 400 mm replacement and original-fit door designed for IEK's FORMAT series of free-standing, floor-mounted low-voltage distribution enclosures. Manufactured by IEK Holding LLC — one of Russia's largest domestic electrical equipment producers — the door is cold-rolled from sheet steel and finished in grey powder coat.
It hangs on four hinges that open to a full 150°, giving unobstructed front access for installation and maintenance. The fully symmetric door profile can be mounted on either lateral plane of the FORMAT frame with no additional adapters, streamlining spare-parts management across multi-bay assemblies.
A perimeter stabilizing rigidity frame runs around the inner face with 25 mm-pitch perforations, enabling direct attachment of DIN rails, cable ducts, and switchgear rated for loads up to 50 kg. A 4-point locking mechanism ensures even closure pressure along the full door height, and a pre-fitted key lock (2-tooth insert, supplied without handle) provides baseline security.
An M8 earthing stud is factory-installed, simplifying compliance with protective-bonding requirements. The FORMAT enclosure system is engineered to support low-voltage complete devices (NKU) at 400/230 V, 50 Hz with current ratings up to 6300 A and sectioning levels up to 4b.
